Chapter 12: Primary canal and Flat canal system in RCS.

12.1. Flat canal system.Flat canal system: It is the canal where the starting and ending of the canal are at the same level. Water entering or exiting from the canal will alter the level of water in the canal.

We may be creating the flat primary canal of the size of 200 mts of breadth and 25 mts of the depth, with the water fill able depth of 20mts, with this each kilometer of FPC will be able to accommodate 0.144 TMC of water.

FPC: Length, Size and Capacity.

Dimension of one Km of actual FPC: L×H×B

=1000mts×25mts×200mts

Dimension of one Km of fill able FPC: L×H×B

=1000mts×20mts×200mts

=3300feets×66feets×660feets

=143748000 cubic feet.

FPC: Length, Size and Capacity.

TMC: Thousand million cubic feet.

=1,000×10,00,000 cubic feet.

=1,000,000,000 cubic feet.

Dimension of one Km of fill able FPC:L×H×B

=143748000 cubic feet.

So, the capacity of One km of fill able FPC

=143748000÷1000000000

=0.144TMC.

This is an example for flat canal system.

Flat canal system needs to get continuous supply of water from the sources where those sources should be able to full fill the water need of the entire nation continuously. For which we need to depend on the water of the continuously flowing rivers like Ganga, Yamuna and Brahmaputra with the water of their tributaries. Some of the methods by which we can bring these water to feed the Flat primary canals are mentioned in the following topics.

12.2. RCS of India in the world.

RCS of India in the world.



RCS of India in Himalaya:

12.3. GRE (Ganga River Elevator).Even though the origin of the River Ganga is at higher level like 7756mts at Gangothri glacier, it becomes as low as 400 to 500 mts AMSL proximal to Hrushikesh. It is not possible to create canal from the higher place keeping in mind to shift the water to south India to feed the drought prone places in the central, northwest and south India. We also know that most of this drought prone area lies below the level of 600 mts AMSL in the central, northwest and south India. So, to shift the water of R. Ganaga, we need go the point in River Ganga where the level of the flow of water higher than 600mts AMSL. Even if we go to the place where the Ganga river is more than 600 mts AMSL, we may not be able to bring the water to the required places of the India because there are Himalayan range of hills present on the south of the R. Ganga, and we need to create a long distance canal for many thousands of kilometres, which is not practical. So, we need to identify a place in the course of the Ganga river, where we can construct a wall across the river (River elevator / a dam like structure, but it is not the dam) and the river to fill the water behind it, thus make its top surface to come up, and create the canal from the top and make the water to flow from the top.

This is the proposed place for Ganga River Elevator, which is at the level of 443 mts AMSL at the banks river Ganga in this place.

The place we propose to construct the GRE, is proximal to the place Rishikesh, at this place the river will be flowing in the narrow valley, so that elevating the river, with minimal length of RE, that is less than one kilometre and there will be less water will stay as the back water in the valley as this entire valley is narrow, and less population is distributed in this place.

Some of the places which comes on the sides of the GRE back water are the Bagi and Teen dhara.

The top of the GRE will be at the level of 950 mts AMSL, and the length of the GRE at the top will be 1.69 kms.

GANGA RIVER ELEVATOR-950-443-950;

12.4. The difference between the river elevator and the dam.The difference between the river elevator and the dam are as follow.

River elevator. Dam / Reservoir.It is constructed across the river.

It is also constructed across the river.

Select the place where the river valley is narrowest.

Select the place where the river flows between two hills.

Storing the water is not the purpose.

Storing the water in the rainy seasons to use it in the summer season is the purpose.

Since it is the narrow place, minimal water will be stored as the back water.

Place is selected in such a way that sufficient water (Capacity of the reservoir) should be stored in the reservoir, so that more water will be available for usage in summer.

The water draining canals begins at the top of the structure / wall / dam like thing. A constant volume of water will be present behind the RE all the time, only the water which fills above the level of the bottom of the draining canal will

The water draining canals are at the bottom of the dam, so that all the water which is stored can be utilised and the dam will be made free to accommodate the water in the rainy season again.

flow in to the canal.The volume of back water will be less.

The volume of the back water is more.

These types of structures will come in the less populated area.

The back water will occupy the more populated areas and thus impose lot of rehabilitation procedures.

Maintenance is easy as it is low pressure system (the water pressure at the top of the structure will less, if some repair work has to be done for the gate), we can make the level low by allowing the river to flow in its natural path.

Maintenance is difficult as it is high pressure system (the water pressure at the bottom of the structure will be high, if some repair work has to be done for the gate), lot of water will flow if the gate gets damaged and repairing the same is a risky procedure. Sometimes we may have to leave all the water before repairing the gate or need to wait till the summer season comes and the level becomes less naturally.

People are not at risk if the gate gets damaged.

People are risky if the gate gets damaged.

12.5. GUC (Ganga Upper Canal) 950-930:The entire course of GUC (Shown in red line);

(GUC End 930)(GUT Start 930)(30000’46.62”N)(780021’33.37”E)

930 GUC ends at this point and from where the GUT starts.

The total length of this Canal Reference Line (CRL) will be will be 113kms. But with the creation of Direct connector 1 and Canal elevator 1 the length of this GUC becomes 39.5kms. So, we can save about 73 kms of canal creation still it receives the water generated in this catchment area. Even though GUC can irrigate the land which is below 900 mts AMSL from the canal called ‘GUC’, but not much agricultural land will be available between the area which is south to river Ganga and north to ‘GUC’, thus GUC will just carry the water till the starting point of ‘GUT’. Ganga upper canal:

Total length: 113kms.

GUC-DC1 length: 0.92kms.

GUC-CE1 length: 2.43kms.

GUC-DC1 saves: 29kms.

GUC-CE1 saves: 47kms.

So, the actual length of GUC becomes: 40.35kms.

12.6. GUT (Ganga – U – Tube): This is the starting point of the GUT.

The starting point of the GUT will be present to the west to the GRE, on the hills which are present south east to the course of the river Ganga.

The entire course of the GUT, which shift the water of the River Ganga from east 930mts AMSL to west 870mts AMSL of the course of the River Ganga, and traverses beneath the river;

It ends little north to the place, kishanpur in Uttarakhand.

The end opening of the GUT is planned in such a way that it ends at the catchment area of the river Yamuna and the water will be flowing in to one of the tributaries of the River Yamuna.

12.7. YUC (Yamuna Upper Canal):The gap which is present between the GUC end and the YUT will be filled by the YUC.

This is the starting point of the YUC.

This is the entire course of the YUC, which runs on the range of Himalaya hills which are present north to the river Yamuna, traversing across the tributaries which joins the river Yamuna from the north.

800 YUC End

The length of the YUC will be 85.70 kms.YUC will receive the water from all its tributaries of River Yamuna which comes and joins it, above the level of 800 mts AMSL. Along the course of the YUC, the water from many tributaries of River Yamuna will fill the water to the YUC, along with the water which is flowing by the river Ganga.

This type of receiving the water from the various tributaries will continue till the end of the YUC and it ends at the southern inclination of shivalic range of hills north to the place Majra and paontosahib.

YUC – CE 1 (Yamuna Upper Canal – Canal Elevator) It is an example to shorten the length of the canal, still it will receive the water from its catchment area.

12.8. YUT (Yamuna U Tube).It is the starting point of YUT at 800mts AMSL, at the southern decline of the shivalic range of hills of Himalaya north to the place Majra and Poanto sahib.

It moves between Jagadri and Indri in the west and Behath and shaharan pur in the east. The course of the canal may be made curved to bypass the major city.

The course continues towards the south, between Karnal and Asand on the west and Gangoh and Panipat on the east.

The lowest point that we come across in course is about 217mts AMSL near Rohtak. The lowest point is placed in such the way that the cleaning maintainace gates at the lowest point will be placed facing west and this water will be flowing towards the west in the Rajasthan.

YUT Lowest point 217:

217) (760043’5.60”E)This is a tentative point. This point may change towards west after doing micro survey, and if the Govt. Of Nepal is accepting to Create the FPC4 at 300mts AMSL, as it is passing through Nepal and we may have to do another U tube for FPC4, close to YUT to by pass this depressed area.

The lowest point in the course of YUT will be 217mts AMSL, which is east to Rohtac, by going towards the west to Rohtac we will get still lower points like 210 to 200 mts AMSL, which is safer to go for such points so that the cleaning maintainace water will reach the Arabian Sea with ease.

It is also necessary to reserve the space for the U tube that comes in the course of FPC4, and it will be moving east to YUT.

Then the YUT will start climbing towards Jaipur hills between Charkidadri and Mahaendragarh on the west and Daola and Rewari on the east.

YUT ends at the level of 700mts AMSL north to Neem ka tana, in Rajasthan, and discharges its water, which is the water of the river Ganga and Yamuna together.

We can see the entire course of the YUC, both the straight and curved course, curved course will bypass all the major cities and towns, and the lowest point of the tube will be towards the west inclined land in the state Rajasthan.

700 Yamuna U Tube ends at this point.

Yamuna U tube length will be 370.00 kms. YUT just acts as the conduct between YUC and FPC1, since it is a closed system, it is not going to receive any water, other than the water of the YUC.The place where the YUT ends and the FPC1 begins is shown here.

The YUT end opening is planned in such a way that, the water from it will fall on the declining surface of the hill, which ultimately will feed one of the water pathways / tributary of the River Yamuna which feeds the River Yamuna from south. We get about 200mts of inclined forceful flow of water in this place and this can be used for Hydro electrical project.

The total length of FPC1 will be 7675.38kms. It has west and east extensions. The length of the west extension will be 967.86 kms and the length of the east extension will be 3889.07kms. Thus the total length of the FPC1 becomes 12532.31kms. FPC1 will receive water from the river Ganga, Yamuna, from all the hills like Aravalli range of hills (all around, above the level of 500mts AMSL), vindya range of hills (from north flowing rivers), Mahadeo hills (from east flowing rivers), maikala and ramgarh hills (all around, above the level of 500mts AMSL), dandakaranya (above the level of 500mts AMSL), satpura – sahyadri – balghat – harishchandra - palkonda range of hills, Bangalore platue, nigiri – palani – cardamom hills by the east flowing rivers above the level of 500mts AMSL. This is going to supply water to all the lands of the India, which are less than 500mts AMSL, except, the areas which are north to Ganga and Yamuna river, north eastern states and Jammu & Kashmir.

FPC 4 – 250 or 300 or other levels will be decided only after discussing the issue with the government of Nepal, as the south border of Nepal is at the low level, which is less than 100mts AMSL, in most of the south border. Thus have not gone in details of this canal, as its level may change as per the cooperation given by the government of Nepal.
