Preface Optimal management of water resources is the necessity of time in the wake of development and

growing need of population of India. The National Water Policy of India (2002) recognizes that

development and management of water resources need to be governed by national perspectives in

order to develop and conserve the scarce water resources in an integrated and environmentally

sound basis. The policy emphasizes the need for effective management of water resources by

intensifying research efforts in use of remote sensing technology and developing an information

system. In this reference a Memorandum of Understanding (MoU) was signed on December 3, 2008

between the Central Water Commission (CWC) and National Remote Sensing Centre (NRSC), Indian

Space Research Organisation (ISRO) to execute the project “Generation of Database and

Implementation of Web enabled Water resources Information System in the Country” short named

as India-WRIS WebGIS.

India-WRIS WebGIS has been developed and is in public domain since December 2010 (www.india-

wris.nrsc.gov.in). It provides a ‘Single Window solution’ for all water resources data and information

in a standardized national GIS framework and allow users to search, access, visualize, understand

and analyze comprehensive and contextual water resources data and information for planning,

development and Integrated Water Resources Management (IWRM).

Basin is recognized as the ideal and practical unit of water resources management because it allows

the holistic understanding of upstream-downstream hydrological interactions and solutions for

management for all competing sectors of water demand. The practice of basin planning has

developed due to the changing demands on river systems and the changing conditions of rivers by

human interventions. The multiple uses of water and varying demands on a river basin require an

integrated approach to managing river basin.

Basin wise report generation is one the important deliverables of India-WRIS project. Report of

Cauvery Basin describes systematically the present status of water resources: major water resources

projects, hydro-meteorological observations, surface and ground water development scenario,

topographic characteristics, climatic variability, land use / land cover pattern & allied natural

resources along with socio-economic profile of the basin. The report contains valuable latest

information of the basin on all aspects of water resources and allied sectors and will be useful as

baseline information for the irrigation officials, hydrologists, agriculturalists, conservationists,

research organizations and all those involved in the development of Cauvery Basin.

Executive Summary This report provides valuable information related to the topography, demography, climate, surface

& ground water resources, hydro-meteorology, water quality and Inland Navigation of Cauvery

basin. The basin covers major part of peninsular India, spreads over states of Tamil Nadu, Karnataka,

Kerala and Union Territory of Puducherry which is nearly 2.7% of the total geographical area of the

country. It extends over an area of 85,626.23 Sq. km with a maximum length and width of 560 km

and 245 km, respectively. It is bounded by the Western Ghats on the west, by the Eastern Ghats on

the east & the south and by the ridges separating it from Krishna basin and Pennar basin on the

north. The basin constitutes of 3 sub-basins namely Cauvery Upper, Cauvery Middle and Cauvery

Lower sub-basin. There are 132 watersheds, each of which represents a different tributary system

for size ranging from 362 Sq. km to 991 Sq. km with maximum number of watersheds falling in

Cauvery Middle Sub-basin. On the basis of the 2001 Census, the total population in this basin is

about 3,18,89,280. Cauvery River which is the main river in this basin rises at Talakaveri on the

Brahmagiri range in the Western Ghats in Karnataka at an elevation of about 1341 m and flows for

about 800 km before its outfall into the Bay of Bengal. The important tributaries joining the Cauvery

are Harangi, Hemavathi, Kabini, Suvarnavathi and Bhavani. In the Cauvery basin, four distinct

seasons occur. They are winter, summer, south-west monsoon, and north-east monsoon season in

this basin. The basin is mainly influenced by South-West monsoon in the Karnataka & Kerala and

North-East monsoon in Tamil Nadu. Rainfall in the delta area is of the order of 1000 mm annually.

The basin has a tropical and sub-tropical climate. In the upper reaches which include Kerala and

Karnataka, the variation in temperature is minimum. The mean monthly temperature over the basin

varies from 22.98° C to 28.43° C. Around 21 land use/land cover classes are existing in the basin.

Agricultural land is dominant in this basin having an area of 53736.30 sq. km. (66.21%) followed by

16636.66 sq. km. of forest area (20.50%). The entire basin falls in three agro-climatic zones which

include west coast plains and ghat region, east coast plain and hill region and southern plateau and

hills region. Out of these, large portion of the basin consists of southern plateau and hills region. The

basin is divided into three agro-ecological zones mainly hot humid pre- humid eco-region with red,

lateritic and alluvium derived soils, hot sub humid to semi-arid eco region with coastal alluvium

derived soils and hot semi-arid eco-region with red loamy soils. About 82.87% of the basin area falls

under moderately shallow to deep (>50 cm) followed by 11.76% area under extremely shallow (<10

cm). Based on soil texture, maximum area falls under fine texture (68.01%) followed by medium

texture (17.90%). Soil erosion is a problem in this basin since 1512659.84 ha area comes under

severe erosion activity comprising of 17.93% of the total basin area. Soil productivity ranges from

highly productive to non-productive area i.e., 26.54% and 13.41% of the basin area respectively.

Major portion of the basin is having gentle slope accounting to 66.60% followed by 12.17% of the

basin having steep slope.

There are 3 sub-basin and 132 watersheds falling in the basin based on SRTM DEM data. During the

pre-plan period many projects were completed in this basin which included Krishnarajasagar in

Karnataka, Mettur dam and Cauvery delta system in Tamil Nadu. Lower Bhavani is one of the

important projects completed during the plan period. Hemavathi, Kabini and Harangi are other

important projects in the basin. According to the assessment, the total utilizable surface water

resource in the Cauvery is 19000 MCM. There are around 42642 surface waterbodies available in the

basin. Number of reservoir falling in the basin are 101; a large number of lakes comprising of 10692

are also present in the basin area whereas 30739 tanks are also present. There are about 29 major


www.india-wris.nrsc.gov.in iv

and medium irrigation projects in Karnataka and 25 major and medium irrigation projects in Tamil

Nadu. There are 15 major hydroelectric projects with 24 power houses available in the basin.

Number of dams falling in this basin are 96 whereas 10 barrage and 16 anicuts or weirs have been

constructed in the basin.

In the Cauvery Lower sub-basin, there are 146 ground water observation wells whereas in Cauvery

Middle sub-basin there are 612 observation wells located and Cauvery upper sub-basin comprises of

115 observation wells. In general, ground water levels in major part of the basin falls between 10 to

20 m bgl, however, in Cauvery delta the water level is less than 10 m bgl during pre-monsoon in year

of 2009. There are a total of 36 hydrological observation sites in the basin maintained by Central

Water Commission. Out of this, 21 sites are GDQ and 15 are GDSQ sites located in the basin. The

basin has good quality of ground water, except salinity near sea shore. Ground water quality

observations are taken at 71 sites of CWC in the basin.

NWDA has proposed 16 peninsular components in the inter-linking of rivers, out of these two are

falling in the Cauvery basin viz. Somasila- Grand Anicut Link and Cauvery (kattalai) – Vaigni-Gundar

Link. There are 60 main tourist places, including many pilgrimages, wildlife sanctuaries, waterfalls,

hill station, forts and lakes etc.

Team India-WRIS hopes that the Cauvery River Basin Report will be a useful asset for the country

and stakeholders and may engrain better understanding of the water resources scenario in the

basin. This report will be a utilitarian for management of water sector in the basin.

1. Introduction

1.1 Overview of basin The Cauvery basin extends over states of Tamil Nadu, Karnataka, Kerala and Union Territory of

Puducherry, draining an area of 85,626.23 Sq.km (GIS Calculated as per India-WRIS Database) which

is nearly 2.7% of the total geographical area of the country with a maximum length and width of

about 560 km and 245 km, respectively. Out of this, 42% area lies in Karnataka, 54% area in Tamil

Nadu & Karaikkal region of Puducherry and 4% in Kerala (Figure 1). It falls in peninsular India and lies

between 75°27’E to 79°54’E and 10°9’N to 13°30’N as shown in Map 1. The salient features for the

basin are described in Table 1. It is bounded by the Western Ghats on the west, by the Eastern Ghats

on the east and south and by the ridges separating it from Krishna basin and Pennar basin on the

north. The three main physiographic division of the basin are the Western Ghats, the plateau of

Mysore and the Delta. The Western Ghat region is mountainous and covered with thick vegetation.

56 m resolution False Colour Composite AWiFS satellite imagery of the Cauvery basin is shown in

Map 2(a). The plateau of Mysore with an average elevation of 750 m slopes gently towards the

east/south-east (Source: Report of the Irrigation Commission, 1972, Vol.III). The delta is the most

fertile tract in the basin and covers some portion of Tamil Nadu and is eminently suited for intensive

cultivation.

The Cauvery River is one of the major rivers of the peninsular India. It rises at an elevation of 1,341

m at Talakaveri on the Brahmagiri range near Cherangala village of Kodagu district of Karnataka and

drains into the Bay of Bengal. The total length of the river from origin to outfall is around 800 km. In

size, it is smaller than the Godavari, the Mahanadi and the Krishna. Its important tributaries joining

from left are the Harangi, the Hemavati, the Shimsha and the Arkavati whereas the Lakshmantirtha,

the Kabbani, the Suvarnavati, the Bhavani, the Noyil and the Amaravati join from right. The utilizable

surface water resource for the basin is 19 BCM. The Average Annual Runoff and Average Annual

Water Potential in the basin are same as 21.36 BCM. The major part of basin is covered with

agricultural land accounting to 66.21% of the total area and 20.50 % of the basin is covered by forest

area. The basin spreads over three sub-basins and thirty six parliamentary constituencies (2009)

comprising eighteen of Tamil Nadu, eleven of Karnataka, three of Kerala and one of Puducherry

(Map 2(b)). These comprises of a total population of 3,18,89,280 spread across the basin area.

Figure 1.State wise basin area

1.2 Topography It is bounded on the west by the Western Ghats, on the east and south by the Eastern Ghats and on

the north by the ridges separating it from the Tungabhadra and Pennar basins. The elevation

variation of the basin is depicted in Table 2. The maximum elevation about 2000-3000m is observed

in 1% of the total geographical area of the basin. Around 32% of the basin area falls under the 750-

1000 m elevation zone (Source: SRTM 90 m). The elevation zones are shown in Map 3.

At Shivanasamudram, the river branches off into two parts and falls through a height of 91 m. in a

series of falls and rapids. The falls at this point is utilised for power generation.The power station at

Shivanasamudram was built as early as 1902.The two branches of the river join after the fall and

flow through a wide gorge which is known as "Mekedatu"(Goats leap) and continues its journey to

form the boundary between Karnataka and Tamil Nadu States for a distance of 64 kms. At

Hogennekkal Falls, it takes southernly direction and enters the Mettur Reservoir which was

constructed in 1934. A tributary called Bhavani joins Cauvery on the Right bank about 45 kms below

Mettur Reservoir.Thereafter it takes Easternly course to enter the plains of Tamilnadu. Two more

tributaries Noyil and Amaravathi join on the right bank and here the river widens with sandy bed and

flows as "Akhanda Cauvery".

The hills forming the Western limits of the basin extend from the past “Bisley Ghat" to the "Jenkle

Betta" and includes peaks like "Puspagiri" or "Subramanya" close to the South-West border rising to

a height of 1715 m. Besides Jenkle Betta at 1389 m, Devara Betta which raises to upto a height of

1282 m and Murukanagudda at 1300 m. Also Indra Betta in Hassan district is 1020 m high and is

noted for 52 feet colossal statue of "Gommateshwara" on its summit. The Melkote range forms a

series of conspicuous hills marked by trignometrical status (Melokota peak) and these are composed

of pink to light grey granite gneisses. Intruding all the rocks are several felsites and porphyry dykes.

The porphyry dykes are situated in the neighbourhood of Mysore city. The delta area in Tamil Nadu

is underlain by formation of Quaternary, Tertiary and Cretaceous age rocks.



The region is chiefly underlain by the Archaean Proterozoic crystalline rocks which constitute

gneisses, charnockites and granites and is covered by quaternary sediments towards the coast. The

river basin falls within two major terrains with its head waters flowing through a greenstone- granite

terrain (Dharwar Craton) in the north and a granulite terrain in the south. These two terrains are

separated by a transition zone of granitic rocks with inclusions of a schist belt towards the north and

charnockites and pyroxene granulites and high grade amphibolite assemblages in the south. The

quaternary sediments are basically fluvial sediments, middle Holocene beach ridges and late

Holocene dune sands. The area is criss crossed by a number of distributaries of the river Cauvery and

few man made channels which bring sediments in to the coastal region. The transition of

geomorphology in this basin is attributed to active faulting, seen together with shift from stable to

an uplifting region with the change in crustal rheology from a cold Archaean cratonic region to a

hotter crust of Pan-African thermal age.

1.3 Climate Climate is a measure of the average pattern of variation in temperature, humidity, atmospheric

pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a

given region over long periods of time. Climate is different than weather, in that weather only

describes the short-term conditions of these variables in a given region.

In the Cauvery basin, four distinct seasons occur. They are Winter, Summer, South-West Monsoon,

and North-East Monsoon. The climate at the basin level generally remains dry except from monsoon

months. There is a considerable variation in the mean daily maximum and minimum temperatures

across the basin. in the cold season, the Western Ghat is cooler than the rest of the basin and the

climate is generally pleasant. In the hot weather season, the Central, Northern and Eastern regions

are hotter than the Western most parts.

The South-West monsoon sets by middle of June and ends by middle of September. During this

season the basin receives major part of its total annual rainfall. The North-East monsoon is from

October to December and is important particularly for the Eastern part of the basin.

However, around 44 blocks of 10 districts falling in the basin are drought prone (Source: Drought

Prone Areas Program, DPAP, MoRD, 2002).

1.3.1 Rainfall

There are many rain gauge stations inside the basin. The rainfall in the basin varies from region to

region. The normal annual rainfall in Kerala region is about 2400 mm. In the Western Ghats it ranges

from 1700 mm to 3800 mm. In Karnataka for the Cauvery basin, the average rainfall is between 600

mm to 800 mm resulting into semi-arid condition. In Tamil Nadu, under the cauvery basin the

average rainfall is low ranging from 500 mm to 1000 mm and is semi-arid. In general, the highest

rainfall in the Cauvery basin usually occur in July or early August and the mean annual rainfall is

around 1075.23 mm.

The basin is mainly influenced by South-West monsoon in the Karnataka & Kerala and North-East

monsoon in Tamil Nadu. Most of the parts in Tamil Nadu receive rainfall from the North-East

Monsoon. Rainfall in the delta area is of the order of 1000 mm annually. In the coastal areas the

highest rainfall months are October, November and December, while further inland the peak

monthly rainfall is early October. This pattern of rainfall is conductive to a fairly high flow during the

irrigation season from June to January, except for a short period of about six weeks when there is a

break in the monsoon. While the South-West monsoon supply is copious and dependable, the

North-East monsoon supply is irregular and subject to frequent failure. Map 4 represents 10 x 10

average annual rainfall of past 35 year (1971-2004).

1.3.2 Temperature

The basin has a tropical and sub-tropical climate. In the Upper reaches (i.e., Kerala and Karnataka),

the variation in temperature is very small. The mean monthly temperature over the basin varies

from 22.98° C to 28.43° C (Figure 2). The northern portions of the basin experience lower

temperatures than the southern. In the monsoon and post-monsoon seasons, temperatures are

moderate and in the range of 25° C to 27.5° C. April is generally the hottest month of the summer

with mean monthly maximum temperature of 34.31° C. January is the coldest month with mean

minimum temperature of 17.15° C. The monthly average mean temperature (1971-2004) is 25.75° C.

Temperatures are higher in the plains (lower reaches) than in the hills (upper reaches). The mean

temperature (Mean of Max. and Min.) in Kerala is below 20°C and in Karnataka it ranges between

20°C to 26°C. The mean temperature in Tamil Nadu is between 26° C to 30° C. The overall mean

maximum temperature for the cauvery basin is 30.56o C and mean minimum temperature is 20.210C.

Figure 2. Monthly average temperature (1969-2004)

1.3.3 Trends and variability

The complexities of the water systems in the Cauvery basin include simulation of sea water rise and

changes in precipitation in the South West and North East monsoon. Precipitation varies

considerably across the basin. The western side of the catchment mainly experiences the south-west

monsoon from June to September and the eastern side experiences North-East monsoon from

October to December.

Trends have been generated based on area weighted average method and regression analysis

techniques. Figure 3 represents spatial depiction of 10 x 10 average annual rainfall of 35 years (1971-



2004). The trend shows that there is significant change in rainfall across the basin. Looking at the

histogram for average annual rainfall general trend, the trend line shows there is a decrease in

rainfall amount since 1971 to 2014. Year 1975 appear highest annual rainfall of 1750 mm. The basin

experience lowest rainfall amount to 700 mm in the year 2003.

Figure 3. Trend of annual rainfall (1971-2004)



1.4 Major rivers The Cauvery River is biggest river in south India. It rises at Talakaveri on the Brahmagiri range in the

Western Ghats in Karnataka at an elevation of about 1341 m above mean sea level and flows for

about 800 km, before its outfall into the Bay of Bengal. The Cauvery river system consists of 21

principal tributaries each with catchment area around 250 sq. km.

The river Bhavani is one of the largest and the second longest river in the basin rises in Kerala and

Karnataka but lies mostly in Tamil Nadu. The longest tributary, the Hemavathi (233 km) is the fifth

largest river in catchment area and lies wholly in Karnataka. It rises in the Western ghats and runs

South-East. After a stream from the West joins it, it turns East, receiving the Yagachi from the North.

It then winds round Holenarasipur and runs South to the Cauvery near Yedatore. The Kabini river is

an important tributary of the Cauvery. It is a perennial river, 150 to 200 m. wide and has a course of

about 240 kms. It rises in the Western ghats in North Wynad in Kerala State as two streams i.e. the

Mannantoddypuzha and Panamarampuzha. About 16 kms. below their confluence, the Kabini forms

border between Kerala and Karnataka for about 12 kms. before entering Karnataka state. It joins the

Cauvery at Tirumakudalu Narasipur (T.N.Pur) and this confluence point is being considered as a spot

of great sanctity. The confluence point is also called as “Triveni Sangama”. The Bhavani is a

picturesque perennial river of South India, rising in Attappadi valley in Kerala. It enters Tamilnadu

near Mannar and traverses from West to East for 234 kms. and joins the Cauvery near Bhavani

Town. It principally receives runoff from the South-West monsoon and occasional floods during

North-East Monsoon. From the point of view of flow contribution to the system, apart from the head

reach of the Cauvery main, the most important tributaries are Amravati, Hemavathi, Kabini, Noyil

and Bhavani. All the distributaries in the region are non-perennial and flow is mainly due to Cauvery

water release during June to January. No considerable flow occurs due to South-West monsoon and

for most of the months in the year, the flow available are the regulated flows from upper regulators

maintained by Tamil Nadu. The total length of the river Cauvery from the head to its outfall into the

sea comprises a length of 320 km in Karnataka 416 km in Tamil Nadu and remaining length of 64 km

forms the common boundary between states of Karnataka and Tamil Nadu (Table 3).

1.5 Land use/land cover The spatial distribution of land use/land cover (2005-2006) was carried by LISS-III data of Cauvery

basin and is shown in Map 5. It is found that nearly 21 land use/land cover classes exist in the basin.

Agricultural land is dominant in this basin having an area of 53736.30 sq. km. (66.21%) followed by



16636.66 sq. km. of forest area (20.50%). The built up area is 4.01% which comprises of 3256.37

sq.km of the total area of the basin. 3133.94 sq. km. wastelands are there in this basin comprising

3.86% of the total basin area (Table 4). The second level categories of land use/land cover in the

basin are fallow land, scrub land, scrub forest, river/stream/canal, rural, urban mining,

swamp/mangrove, etc.

Its vast fertile alluvial tracts and low hills with suitable climatic condition offer excellent condition for

utilization of land for different uses. The land use pattern of the basin witnessed a change in last few

decades. The fast growing population aided with the modern technology lead to rapid change in the

land use pattern of the basin. The effects such an unwise change is well reflected in the forms of

ecological imbalance and land degradation through soil erosion. The forest area has been decreasing

due to the encroachment for agricultural. The horizontal growth of settlement in the last few

decades due the rapid growth of population and the resultant growth of other developmental

activities also leading to a slow but continual change to the land use pattern at different scale.

There are mainly three crop seasons in the basin viz. kharif, rabi and summer. The kharif crops are

paddy, bajra, jowar, maize, ragi, cotton, millets etc. Paddy is the most important crop in this basin,

whereas Ragi, Jawar and other millets constitute the important crops under rainfed conditions.

Coconut, betel leaves, pepper, oranges and lemon are grown as horticulture crops throughout the

year. The main forest products are sandalwood, bamboo, teak, eucalyptus, blue gum and wattle etc.

1.6 Soils Soil is composed of minerals, mixed with some organic matter, which differ from its parent

materials in terms of its texture, structure, consistency, colour, chemical, biological and other

characteristics. Information on the soil profile is also required for simulating the hydrological

character of the basin. The principal soil types found in the basin are clay, loamy clay, sandy clay,

silty clay, loamy sand, sand, loam, sill loam, silt, sandy loam and rocky. The soil productivity of the

basin is categorized into highly productive, low productive, non-productive and moderately

productive. The soil in the basin is classified into moderate, slight and severe and the major soil

slope classes are gently, steep, moderately and nearly leveled.

The highly productive and fertile soils of the basin are now facing the serious problem of soil erosion

like other parts of the country. Under heavy precipitation and humid climate loss of top soil through

surface run-off is the most common type of soil erosion in the entire basin. The delta area is the

most fertile tract in the basin. The principal soil types found in the basin are black soils, red soils,

laterites, alluvial soils, forest soils and mixed soils. Red soils occupy large areas in the basin. Alluvial

soils are found in the delta areas of Cauvery which is the most important agricultural tract in the

basin. In addition to the distinct soil types described above, combinations of these types such as

mixed red and black soils, etc. also occur.

The main soil types based on texture, erosion, productivity and slope are spatially depicted. About

82.87% falls under moderately shallow to deep (>50 cm) followed by 11.76% extremely shallow (<10

cm) based on the depth of the soil. Based on soil texture, maximum area falls under fine texture

(68.01%) followed by medium texture (17.90%) as shown in Map.6. Soil erosion is a problem in this

basin since 211357.95 ha area comes under very severe erosion activity comprising of 2.50% of the

total basin area. 1512659.84 ha (17.93%) area comes under severe condition and about 50.33% area

of the basin which constitutes 4246760.29 ha have moderate erosion as shown in Map 7. Major

portion of the basin is having gentle slope accounting to 66.60% followed by 12.17% having steeply

sloped as shown in Map 8. Soil productivity ranges from highly productive to non-productive area

i.e., 26.54% and 13.41% of the basin respectively as shown in Map 9.

1.7 Agro-climatic zones The agro-climatic classification is an extension of the climate classification keeping in view the

suitability for agriculture. For resource development, the country has been broadly divided into 15

agricultural regions based on agro climatic features, particularly soil type, climate including

temperature and rainfall and its variation and water resources availability.

There are basically three zones falling in Cauvery basin which includes west coast plains and ghat

region, east coast plain and hill region and southern plateau and hills region (Map 10).

Out of these, large portion of the basin falls in southern plateau and hills region which is suitable for

cultivation of variety of crops. The climatic pattern of this basin is characterized by the moderate

rainfall, forest cover and soil erosion. This agro-climatic zone is also important for improvement of

cropping systems, development of land and water resources, animal husbandry and fisheries

activities, each one having special characteristics of its own. The main characteristics of the agro-

climatic zones of the basin are describes below:

Southern Plateau and Hills Region: The maximum part of the basin is covered by this region and

comprises of southern part of Karnataka, the central parts of Tamil Nadu falling, parts of Kerala in

the basin, which are typically semi-arid zones.

East Coast Plains & Hills Region: This region covers small area of Tamil Nadu falling in the basin. In

this region soils are mainly alluvial and coastal sands and Irrigation is done through canals and tanks.

West Coast Plains and Ghat Region: The minimum part of the basin is covered by this region

comprising of hilly area of Karnataka, Kerala and Tamil Nadu. Variety of crop patterns, rainfall and

soil types exist in the zone.

1.8 Agro-ecological zones India has a variety of landscapes and climate conditions and this is reflected in the development of

different soils and types of vegetation. Based on 50 years of climate data and an up-to-date soil

database, the country has been divided into 20 agro-ecological zones (AEZs). Each AEZ is as uniform

as possible in terms of physiography, climate, length of growing period and soil type for macrolevel

land-use planning and effective transfer of technology.

The basin is divided into three agro ecological zones mainly hot humid pre-humid eco-region with

red, lateritic and alluvium derived soils suitable for cultivation of paddy, tapioca, coconut, spices; hot

sub humid to semi-arid eco-region with coastal alluvium derived soils having crop intensity of paddy,

coconut, black gram, lentil, sunflower and groundnut and hot semi-arid eco-region with red loamy

soil giving fertility to some of the major crops like millets, pulses, oilseeds(groundnut), sugarcane

and paddy as shown in Map 11. Large portion of the basin area comprises of red loamy soil which

comes under semi-arid eco-region.

1.9 Demography Demographics are the quantifiable statistics of a given population. Demographics are also used to

identify the study of quantifiable subsets within a given population which characterize that

population at a specific point in time. Demographic data is used widely in public opinion polling and

marketing. Commonly examined demographics include gender, age, ethnicity, knowledge of

languages, disabilities, mobility, home ownership, employment status, and even location. The

administrative & demographic details of cauvery basin are listed in the Annexure-I.

A major factor affecting forest cover is the growth of human populations throughout the cauveri

region and the growing pressure that additional people place on the region’s forests. While

urbanization has been growing rapidly over the past few decades at a rate, in many states of the

basin, the rural population has also been expanding by a fast rate. The increasing population and

population density trends are reflected in the per capita availability of forestland. This reflects the

combined impact of population growth and forestland loss. The decadal growth rate has shown a

sharp decline in this zone to 11.19% from 17.25% compared to all India decadal growth of 21.34%

during 1991–2001. The literacy rate has improved to 73.47%, 65.38% and 67.07% in Tamil Nadu,

Andhra Pradesh and Karnataka respectively as against the national average of 65.38%.

The city of Bangalore is partly situated in the basin having a population density of 1500-5000.

Maximum numbers of districts are falling in the density range of 200-500. Important industries in the

basin include cotton textile industry in Coimbatore and Mysore, cement factories in Coimbatore and

Trichinapally and industries based on mineral and metals. The Salem steel plant and many

engineering industries in Coimbatore and Trichinapally are also situated in this basin. As per Census

data 2001, the total no. of villages falling in the Cauvery Middle Sub-basin is 8306, for Cauvery Upper

Sub-basin number of villages are 3339 and for Cauvery Lower Sub-basin it is 2990. The total

population in this basin is 3,18,89,280 and the district-wise population density in the basin is shown

in Map 12.



Map 12. Population density



2. Hydrological units

2.1 Sub-basins Semi-automated approach for delineation of hydrological units (basin, sub-basin and watershed)

uses SRTM DEM, topo maps on 1:50000 scale, IRS P6 LISS IV & CARTOSAT-1 merged data, drainage

network, surface waterbodies, rail/road network and other ancillary data. Drainage divides from

contour/ridge lines are used to demarcate the boundary of hydrological units. The divide has been

marked where flow is in opposite directions. Knowledge of terrain as well as DEM is essential for

accurate demarcation of boundary. Hydrological boundary has been validated with reference to

contours and drainage network. Hydrological unit boundary cuts perpendicular to the contour lines

but it does not cross the drainage line at any location except its outlet. This approach is potentially

more objective, repeatable and cost-effective.

The Cauvery basin constitute of three sub-basins- Cauvery upper, Cauvery middle and Cauvery lower

sub-basin, as shown in Figure 4. Cauvery upper sub-basin covers an area of 10958.8 sq. km. and

consisting of 18 watersheds, Middle sub-basin having an area of 57280.98 sq. km and consisting of

86 watersheds and Lower sub-basin covering an area of 17386.45 sq. km. and consisting of 28

watersheds. The dependable yield for the basin is utilized under number of major, medium and

minor irrigation projects of the basin. Irrigation is being carried out in the area under these projects

viz., dams, barrages, diversion structures and other lift irrigation systems.

Figure 4. Sub-basins and Percent drainage area



2.2 Watersheds Hydrological unit wise assessment of water resources is a prerequisite for its proper management as

it is fast becoming scarce in India. Sub-basins could be sub divided into smaller hydrological units

namely, watershed for water resources management at larger scale. Watershed is a natural

hydrological entity that covers a specific areal expanse of land surface from which rainfall flows to a

defined drain, channel, stream or river at any particular point. Watershed should be delineated

purely on the basis of hydrologic principles. Size of the watershed is governed by the size of stream

and its boundaries.

Three sub-basins have been further divided into 132 watersheds each of which represents a

different tributary system for size ranging from 362 km2 to 991 km2 with maximum number of

watersheds falling in Cauvery middle sub-basin. Maps depicting sub-basin wise watershed

distribution are shown in Map 13(a, b & c). Number of watersheds and the range of size for the sub-

basins are given in Table 5.

3. Surface water resources

3.1 Surface waterbodies Surface waterbodies have traditionally played an important role in the basin,which is used for

irrigation, drinking water supply, ecology, tourism and other domestic uses. But waterbodies (total

number, capacity and quality) are decreasing day by day due to mainly siltation and disposal of

untreated waste in that waterbodies. The details of the surface water resources of the Cauvery basin

are listed in the Annexure-IV.

Surface waterbodies are impounded in the form of reservoirs, lakes, ponds, tanks, abandoned

quarry, aquaculture, cooling pond, lagoon and salt pan. A large scale inventory of surface

waterbodies is required in order to keep it healthy (both quantitatively and qualitatively) and

rejuvenate wherever necessary. The basin is blessed with optimal amount of rainfall. Storage of

water in pond both in the settlement and agricultural fields is the one water saving/storing strategy

of the local population of this basin. It is observed that there are sufficient number of ponds in this

region followed by lakes which is generally used for fish cultivation and agricultural activity. Several

large reservoirs of considerable size have also been constructed in the basin associated with the

dams and barrages. The major reservoirs in Cauvery basin are Krishnaraja Sagar, Mettur (Stanley),

Hemavathy, Kabini, Lower Bhavani and Grand Anicut. The details of different surface waterbodies

are shown in Figure 5.

Around 42642 waterbodies are present in the basin of varying size. No. of waterbodies covering an

area of 25 ha are about 41296 whereas 7 big waterbodies are there covering an area of more than

2500 ha. A detail of number of waterbodies according to their water spread area is given in Table 6.

3.2 Water resource projects Water resources schemes and projects are multi-disciplinary in nature and are implemented by

several departments and agencies of State Governments and various ministries/departments of

Central Government. Water resources projects are broadly categorized into irrigation projects and

hydroelectric projects. The water resources of the Cauvery basin are well developed. The issues of

water resources in the Cauvery are complex and include flood and drainage problems, lack of

freshwater, salinity intrusion of surface and ground water and over abstraction of ground water. The

sustainable management of water resources in the Cauvery Delta requires a wide range of different

approaches involving different sectors. Major water resources project in this basin are Hemavathy,

Kabini, Harangi, Votehole, Uduthorehalla and Karapuzha Irrigation Project. Annexure IV shows CCA

and UIP of some of the projects in the basin of major commands in the basin. During the plan period

many projects were taken up and completed.

3.2.1 Major and medium irrigation projects

There are about 29 Major and Medium Irrigation Projects in Karnataka and 25 Major and Medium

Irrigation Projects in Tamil Nadu. Besides the above, there are series of 10 masonry Anicuts

constructed across the main Cauvery River and some of its tributaries in Tamil Nadu. The areas

getting benefited from these channels in Karnataka lie mainly in Mysore, Mandya and Hassan

districts and to a small extent in Kodagu and Bangalore districts. Large areas in Tanjore and

Tiruchirapalli districts of Tamil Nadu are benefitted through the canal system taking off from Grand

Anicut and Upper Anicut.

3.3.4. Command area and canals network

Canals are man-made channels for conveyance of water. When the water is to be transported across

landscape to deliver the water to the respective command areas by canal network, construction of

various irrigation structures are necessary to negotiate terrain including drains, road, rail lines.

Important irrigation structures are Regulators, Bridge, Aqueduct / Syphon Aqueduct, Super passage /

Syphon, Level crossing / Inlets and Outlets, and Other Cross drainage Structures. Distributary head

regulators control the supply to an off taking channel from the parent channel.

In Cauvery basin there are few completed and ongoing major irrigation projects. Cauvery delta major

irrigation project, Hemavathi major irrigation project, Cauvery Mettur major irrigation project,

Parambikulam Aliyar major irrigation project, Krishnaraj Sagar major irrigation project and Harangi

major irrigation project which is an ongoing project are those major projects having considerable

command area falling within the cauvery Basin. Map 15 is showing the major and medium command

area map of cauvery Basin. All the major command areas of the Cauvery basin are irrigated by

constructing diversion structures like weir and barrage.

The cauvery basin has the largest irrigation canal system in the Tamil Nadu plain. The Grand Anicut

canal irrigation covered land in Mannargudi and Arantangi taluks (Thanjavur). Further down the

Kattalai High level scheme, taking off from the head sluice above Kattalai bed regulator, benefits in

Thanjavur and Tiruchchirappalli district. The Pullambadi canal also irrigates part of the Cauvery

basin. The Baipar and Chittar along with the Tambraparani irrigate a considerable area in

Ramanathapuram and Tirunelveli districts.

Yagachi is an ongoing major Irrigation Project of Karnataka having considerable command area

benefitting the district of Hassan. Yagachi major irrigation project have a culturable command area

of around 21.25 th ha and an ultimate irrigation potential of 21.45 th ha providing support to a large

portion of the area for irrigation.

The Cauvery delta major irrigation project falling in the basins of Cauvery and east flowing region

from Pennar to Kanyakumari has an ultimate irrigation potential of 504.64 th ha and a largest

culturable command area of 368 th ha in this basin assisting large area of irrigation in the districts of

Thanjavur and Karaikal.

Hemavathy major irrigation project with culturable command area of 283.58 th ha and ultimate

irrigation potential of 283.60 th ha is also an important project of the basin providing valuable profit

to the districts of Hassan, Mandya, Tumkur.

Cauvery Mettur Major Irrigation Project is an important project of Tamil Nadu with some related

structure like grand anicut and mettur da associated to it. It provides an ultimate irrigation potential

of 111.70 th ha and covering a culturable command area of 103.60 th ha benefitting the districts of

Thanjavur, Pudukkottai.

A study was carried out jointly by CWC & ISRO to assess the existing status of the irrigation

commands. IRS P4 LISS III data of two different seasons namely, pre monsoon (2005) and post

monsoon (2004) were used for delineation of waterlogged and salt affected areas of major and

medium irrigation commands of the basin. Total waterlogged area within these occupies 21969.33

ha whereas salt affected area has been extended to 14038.85 ha.

3.3.5. Multipurpose projects

Cauvery Basin is gifted with number of rivers and other water resources so the utilization of them

has been taken cautiously and precisely. There are four multipurpose projects going on in this basin.

The Harangi Multi Purpose Project is one of the major project of cauvery basin having gross storage

capacity of 240.7 MCM and Live storage capacity of 228.6 MCM. The project is used for power

generation as well as irrigation purposes. The other important multi-purpose projects in the basin

are Kabini, Bhavani sagar, Mettur multipurpose projects serving the basin with its purposes.

3.3.6. Interstate projects

There is one major Interstate project in the basin - Cauvery Delta interstate project falling in Tamil

Nadu and Puducherry states. This project is is benefitting a large population for irrigation purposes

in both the states.



4. Ground water resources

4.1 Ground water observation wells Water is essential to sustain agricultural growth and productivity. Ground water is the water below

the surface of the earth that occurs in soil pores and in cracks and fissures in rocks. Typically, ground

water is liquid flowing water but the definition also includes soil moisture, perma-frost (frozen soil)

and water trapped in very low permeability bed rocks. A unit of rock containing a usable amount of

water is termed as an aquifer. Ground water is refurbished from the surface and eventually flows

back to the surface in the form of springs or oases. The occurrence of ground water generally

depends upon the rainfall, drainage, topography and the geological conditions of the area.

Ground water plays a key role in meeting the water needs of various user-sectors ranging from

agriculture to domestic as well as commercial use. In the Cauvery Lower Sub-basin there are 146

ground water observation wells whereas in Cauvery Middle Sub-basin there are 612 observation

wells located and Cauvery upper basin comprises of 115 observation wells which are depicted in the

Table 9 and spatially shown in the Map 17. These observation wells are equally distribute in the

entire basin.

The ground water occurs in the weathered gneisses, granites and in joints, fractures and shear zones

of fresh rocks. The yield of wells in these rocks varies from place to place depending on various

factors like the nature of the rocks, the amount and depth of weathering, joint patterns etc. Water

can be tapped in Archaean rocks generally ranged in depth from 6 to 21 m and sometimes to 27 m.

depths to water level in these rocks range between 4.5 and 4.0 m below the ground water. Up the

slope towards north westerly direction, there is lesser and lesser ground water being used for

domestic, industrial and other uses.

Ground water is also often withdrawn for agricultural, municipal and industrial use by constructing

and operating extraction wells. The dependability of ground water is further increased by the vagary

of monsoon as well as poor intensity of rainfall in the delta. This situation had put people to lots of

hardships affecting even the drinking water supply in addition to agricultural instability.Ground

water is used for mainly two purposes at large scale in the basin which includes Drinking and

Irrigation.

4.2 Ground water level fluctuation The occurrence of ground water generally depends upon the rainfall, drainage, topography and the

geological conditions of the area. Ground water fluctuation in the Cauvery basin is assessed for

recharge and draft conditions based on the available ground water level in four different seasons.

Ground water recharge is estimated by the difference in ground water level between pre and post

monsoon seasons. Similarly, groundwater draft is estimated by the difference between post-

monsoon and post-monsoon (rabi) seasons data. Interpolated maps for ground water recharge and

irrigation draft (rabi) are prepared based on the available ground water fluctuation data in the basin.

Any phenomenon, which produces pressure change within an aquifer, results into the change of

ground water level (source: http://drsksingh.tripod.com/gwlevel.htm). These changes in ground

water level can be a result of changes in storage, amount of discharge and recharge, variation of

stream stages and evaporation. External loads such as tides, trains, atmospheric pressure and

earthquake are born in part by the ground water of confined aquifers. Hence they affect peizometric

levels. The general consideration is that due to any reason if the aquifer pressure raises above the

atmospheric pressure an upleveling in ground water level results and vice- versa.

Water table undergoes a seasonal fluctuation following a natural cycle (source:

http://www.indiawaterportal.org). Water table rises during rainy season due to recharge received

from rainfall and falls back during summer season due to lack of recharge and continuing extraction

of ground water. In geohydrology, the highest water level is referred to as the post-monsoon water

level and the lowest level in summer as pre-monsoon water level. The difference between highest

water level value and lowest water level value is termed as fluctuation in ground water level; this

value can be positive as well as negative depending upon various factors.

In general ground water level in major part of the basin falls between 10 to 20 m bgl, however, in

Cauvery delta the water level is less than 10 m bgl during pre-monsoon in year 2009. The ground

water level fluctuation maps (2011) shows that there is a fall of <2m ,fall 2-4 m, fall>4m at different

places in the Cauvery basin while at some places there is positive change in water level fluctuation

(recharge) ranging from 2 to 4 m. The rise in water level is maximum in Cauvery lower sub-basin. The

water fluctuation due to draft is positive in major part of Cauvery middle sub-basin as well in

Cauvery lower sub-basin while in Cauvery upper sub-basin fall is noticed in the range from 2 to 4 m

depending on terrain. The fluctuation due to recharge and draft in the Cauvery basin is shown in the

given below Map 18 & 19 respectively.

4.3 Litholog well locations

An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials

(gravel, sand, or silt) from which ground water can be extracted using a dug well or borewell.

Related terms include aquitard, which is a bed of low permeability along an aquifer and

aquiclude (or aquifuge), which is a solid, impermeable area underlying or overlying an aquifer. If the

impermeable layer overlies the aquifer layer, pressure could cause it to become a confined aquifer.

Aquifers may occur at various depths(source: http://www.ijsciences.com/pub/pdf/V220130908.pdf).

Those closer to the surface are not only more likely to be used for water supply and irrigation, but

are also more likely to be tapped up by the local rainfall. Alluvium, sandstone, loose sand/gravel etc

are the better aquifer material. In hard rock area; fracture/lineament plays an important role in

identifying ground water potential areas. The information on the aquifer material, depth and

thickness of the aquifer layers in a basin can be analysed based on the available lithlog information.

There are 354 litholog well locations exists in whole basin (as per available records) out of which 145

well locations fall in Cauvery Lower sub-basin while 210 well locations fall in Cauvery middle sub-

basin. The litholog well locations is listed under, Annexure V under the heading “Inventory of litholog

well locations”.

The major lithology groups found in the basin are granite gneiss, biotite gneiss, sand with clay and

sandstone, sand clay gravel and sandstone etc. Major rock group encountered in basin is Crystalline

Rocks (Archaean-Pre-Cambrian) and Semi-Consolidated Sediments (Carboniferous-Pliocene and

other ages). The well type which is used for lithological studies with their locations in the basin is

shown in the Map 20.

5. Hydro-met observations

Map 21. Hydro observation stations



5.1 Hydrological observation sites Hydrological observation in the basin is carried out by the Central and State Governments. The

information about various hydrological observation parameters such as gauge (river water level),

discharge (amount of water released from a cross section in the river in a given time period) and

sediment (concentration of solid particles in water) are released time to time by observing stations

of CWC. It has contributed substantially in the collection of hydrological data all over the Cauvery

basin. Being the apex national body for the development of surface water resources of the country,

CWC has established a network of hydrological observation stations across the entire river in this

basin. These stations are categorized as ‘GDSQ’, where the abbreviation stands as: G-Gauge, D-

Discharge, S-Sediment and Q-Water Quality. RF stands for rainfall measuring station.

The CWC maintains 36 gauge-discharge sites in the basin. These sites fall under Cauvery basin sub

zone and east coast sub zone. From some of these sites, sediment observations are also taken. The

Central Water Commission has 21 observation sites for Gauge Discharge Water Quality (GDQ), while

for Gauge Discharge Sediment and Water Quality (GDSQ) the numbers of observation sites are 15 as

shown in the Table 10. The data and observations recorded at these sites are used to understand the

river dynamics of the basin. There spatial distribution for the stations is shown in Map 21. The details

of the attributes related to these sites like Station Name, Station type, Independent river, status etc.

are listed in Annexure VI under heading Salient features of hydro-observation stations.

5.2 Meteorological stations The Hydro-meteorological data pertaining to the river basin is required for modelling the catchment.

These include daily rainfall, maximum and minimum temperature, solar radiation, relative humidity,

wind speed and others. There are three main organizations in our country which records

meteorological parameters viz., India Meteorological Department (IMD), Central Water Commission

(CWC) and ISRO (Automatic Weather Stations).CWC has established 35 Meteorological stations in

the basin. These stations are established to understand the relationship between meteorological

parameter and river dynamics. The basin has 183 Indian Meteorological stations (IMD). The

integrated approach of measuring meteorological parameter using Automated Weather Stations

(AWS) is helpful in the remote region. AWS stations require a minimum maintenance and the data is

generated on the temporal basis. These stations are maintained and data stored by the MOSDAC,

SAC Ahmedabad. Under the supervision of ISRO there are 63 AWS station established in the basin

(Table 11).

6. Water quality

6.1 Surface water quality observations Surface water has played an important role in the development of human civilization. Good quality

water resources depends on a large number of physico-chemical parameters and the magnitude and

source of any pollution load; and to assess that, monitoring of these parameters is essential. Cauvery

and its tributaries are one of the main and important sources of water for a large population in basin

for drinking and irrigation and its quality directly affects their lives. Central Water Commission

operates 36 stations which carry out observations for testing the surface water quality with 68

water quality parameters, which are considered to be the ‘Standard Hydrology Project Water Quality

Parameters’.

All physical, chemical and biological water quality parameters are categorized further under sub

categories like field determinations, nutrients, organic matter, alkalinity, hardness, other inorganics,

major ions, coliforms and others. The ranges of water quality observed in Cauvery basin with respect

to pH, electrical conductivity, DO, BOD, COD, Total Coliform (TC) and Faecal Coliform (FC) are

presented as minimum, maximum and mean value to assess the extent of water quality variation

throughout the year. The untreated sewage waste and effluents of major towns situated along the

river also flow into the main stream of river and degrade its quality for use in irrigation and drinking

purposes.

6.2 Ground water quality observations

The ground water quality at observation wells located in the basin, which measures 15 parameters

viz., pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Magnesium, Nitrate, Potassium,

Sulphate, Calcium, Sodium, Carbonate, Bicarbonate, Chloride, Fluoride, Sodium Absorption Ratio

(SAR) and Residual Sodium Carbonate (RSC) and heavy metals like Arsenic & Iron. They are further

classified in two categories viz. irrigation and drinking water quality standards as described by

Bureau of Indian Standards (BIS) for Ground water quality. They are further classified in two

categories viz. Irrigation and Drinking Water quality standards as described by Bureau of Indian

Standards (BIS) for Ground Water Quality. Based upon all these parameters, the chemical quality of

ground water, both from near-surface and deeper aquifer zones, is generally good and suitable for

the irrigation and drinking purposes in the basin.

There are 71 ground water quality locations present in the basin and monitored by Central Ground

Water Board (CGWB). The physical and chemical properties of ground water were measured by

CGWB in this basin.



7. Inter-basin transfer links India has substantial water resources potential but its availability in various parts of the country is

highly uneven. Inter-basin transfer link proposes river water transfer from the region of surplus to

deficit areas. This may provide an effective way to enhance irrigation potential, to mitigate floods

and droughts and reduce regional imbalance by way of additional irrigation, domestic and

industrial water supply, hydropower generation, navigational facilities, etc. There are two inter-

basin transfer links falling in this basin.

NWDA has proposed 30 possible links in India which include 14 Himalayan components and 16

Peninsular components. Two of those are proposed in the Cauvery Basin (Map 22).

Somasila- Grand Anicut Link

This link envisages diversion of 8,565 MCM of water from Somasila reservoir at Pennar Basin to

South of Pennar to irrigate 4.91 lakh Ha (0.49 lakh Ha in Andhra Pradesh, 4.36 lakh Ha in Tamil

Nadu and 0.06 lakh Ha in Pondicherry). Total length of link canal is about 529 km.

Cauvery (Kattalai) – Vaigni-Gundar Link

The Kattalai Vaigai Gundar Link envisages tapping of 2,252 MCM of water from Cauvey basin at the

existing Kattalai bed to irrigate 3.38 lakh hectares area of Tamil Nadu up to Gundar River. Total

length of link canal is about 255.60 km.

8. Water tourism sites Since the area is situated in the tropical zone, it enjoys a subtropical to temperate climate by virtue of

its altitude and this has contributed to development of the basin as a well-known tourist place. There

are 55 main tourist places including many pilgrimages, wildlife sanctuaries, waterfalls, hill station,

forts and lakes as shown in Table 12 and its spatial distribution is shown in Map 23.

The basin hosts a rich environment for water tourism sites. Wildlife sanctuaries and National Parks,

namely Bannerghatta National Park, Biligiri Rangaswamy Temple (BRT) Wildlife Sanctuary, Point

Calimere Wildlife Sanctuary, Wayanad Wildlife Sanctuary, Adichunchanagiri Peacock Sanctuary etc.

are located in the basin. Islands such as Kuruvadweep and Mananthavady are also situated here. The

Velankanni Matha Church, Shettihalli Submerged Church, Nagore Dargha, Ayappa Temple,

Somnathpur Temple, Lakshmi Kantha Swamy Temple, Bhagamandala etc. are the religious

destinations and Kovai Kuttralam Fall, Iruppu Falls, Abbey Falls and Catherine Falls etc. are some of

the waterfalls that are situated in the basin.

9.Conclusion The Cauvery and its tributaries are inter-state river system, flowing through the states of Kerala,

Karnataka, Tamil Nadu and parts of Puducherry. A number of small and large projects have already

been constructed in the basin and few are under construction. The surface water potential in the

basin is nearly utilized, but there is a need to make arrangements for use of full potential of ground

water. Systematic and scientific exploratory work is needed for a quantitative and qualitative

assessment of the ground water resources in the basin, so that these resources may be exploited in a

rational way, either independently or in conjunction with surface waters. There is need for interstate

cooperation and agreement in respect of carrying out soil conservation measures to conserve the

storage capacities of the existing and proposed reservoirs in the basin. It is necessary for systematic

data to be collected with regard to the sediment carried by the rivers, which would illustrate the

effect of any soil conservation works carried out in the basin.

With an overview of the various environmental issues, it's time to seriously think about the efforts

needed to bring back the original balance in our environment. Ecology, environment and human

beings have to form a synchronous and healthy relationship for them to have any meaning at all.

Realization that, one without the other may not be able to survive has to dawn on one and all. Any

dilly-dallying on the matter could harm us and put us beyond redemption. Old approaches may have

to be reformed, new technologies like for instance remote sensing, have to be harnessed, our

people's attitudes have to be changed. It's only then can we hope to see any difference in the

harmed atmosphere. As of now, the stresses on our environment are many. Some of them we list

here to highlight the need for prioritisation for action.
