KBJNL/FAO RAP-MASSCOTE Training Workshop on Irrigation Management Modernization
Naryanpur 31st January -10th February 2009
The objectives of the Workshop
• Produce insights on the performance of
management in Narayanpur irrigation systems
• Increase capacity on techniques and modern
approaches of management and operation (60
participants).
• Produce some recommendations for the follow-
up of irrigation modernization development
plans at state level.
Tools used: MASSCOTE & RAP

STEP 1 RAP: Objectives
• Provide a basis for making specific recommendations for modernization and improvement of water delivery service, identifying weaknesses and changes
• Provide a baseline for comparison of future performance after modernization
• Benchmarking for comparison against other irrigation projects

RAP Outputs
• External indicators
– Examine inputs and outputs of the whole project (and
constraints)
• Internal indicators
– Identify key factors related to water control throughout a
project.
– Define level of water delivery service provided to users at
all levels of the system
• Managers, operators, WUCS, farmers
– Examine specific hardware and management techniques and
processes used in the control and distribution of water.
RAP Process• We divided into 7 groups
– Group 1:RLIS and NRBC
– Group 2:IBC 0 to 80 KMs
– Group 3:NLBC 77 KMs
– Group 4:SBC 76 KMs
– Group 5: JBC 78 KMs and MBC 51 KMs
– Group 6: IBC 80 to 172 KMs
– Group 7: ILC 0 to 97 KMs– We spent 3 days on the field
• We gave ratings to all internal indicators
• We reviewed and finalized the results in plenary
Our ratings, given, validated and
endorsed by all participants
Common findings (1)
• Huge water infrastructure : should be well managed to
serve generations to come, avoid food shortage and
generate good incomes for rural people.
• Management shift from construction phase to water
management has not yet happened.
• Distortion of reality at management and users levels
• Measurements, assessment and monitoring not given
priority
Common findings (2)
• Multiple Uses of Water: Hydro – Domestic to towns –
domestic to villages /to people – Environment –
Fishing.
• Involvement of all users and stakeholders should be
increased in water management.
• Spreading water all over is good for easy access to
water services , but shallow water stagnation is seen in
several pockets of command with invasive vegetation.
• Drainage flow important (Nala): Water losses !
• Water Services should thus include drainage.

Common findings (3)
• In some subsystems about 50 % rice cultivation
• Water distribution not well controlled
• Rotation not followed leading to shortage of water at tail.
• Lack of gates below disty heads making rotation impossible
• Low flow spreading all around ➔ low efficiency of transport
• Seepage losses as canal lining deteriorated
• Too much water flows in upstream distys.
• Inequity ➔Tail-enders deficit within Disty
Specific findings (1)
NLBC:
❖ Vulnerable reaches in banking in km.61 to 63 needs
special attention for stabilization.
❖ Aqueducts need restoration
NRBC:
❖ Transitions between cutting and banking reaches of
canal need stabilization
❖ Sensitive off-takes need immediate attention
Specific findings (1)
ILC (Lift)
❖ Bank slides in intake channel is a serious problem
RLIS (Lift):
❖ Butterfly Valve required to throttle the discharge
❖ Capacitor to improve Power Factor
IBC (Branch Canal):
❖ Slippage of CC lining to be rectified in many reaches
Specific findings (1)
SBC(Branch Canal): ❖ Excess drawal leads to drainage problem in initial
reaches
MBC(Branch Canal):❖ Substantial leakage in head regulator (diversion). Need
proper structure to automate operation to avoid vandalism
❖ Restoration of aqueduct in km.40 is required
JBC(Branch Canal):❖ Deteriorated lining in initial 20 km stretch to be
rectified

MASSCOTE STEP 2
CAPACITY & SENSITIVITY
Objectives: Assessing the physical capacity of
irrigation structures to perform their function of
conveyance, control, measurement, etc.
Assessing the sensitivity of irrigation structures
(offtakes and cross-regulators), identification of
singular points. Mapping the sensitivity of the
system.
MASSCOTE STEP 2
CAPACITY
Storage is sufficient but NO online storage
Conveyance system is OK.
Some reduced capacity due to siltation.
Some sections affected by seepage
Diversion OK
Distribution OK
Control of water level deficient
Measurements: Deficient rated section
Safety: not enough escapes
Transmission OK
SR along main canal is in good condition . 50 % is good.

Sensitivity characterizes the way structures respond when they are
operated or stimulated by an external cause.
Hydraulic behavior: Sensitivity of
irrigation structure
A variation of water level in the MC ➔ variation of head at near by offtake
➔ variation of the offtaking discharge
an alternative way of looking at fluctuations in irrigation
systems without having to resort to the difficulty of
unsteady flow.
It is a simple “What-If” analysis, i.e. what would be the
change of the output if the input change is so much.
INPUT Variation
OUPUT of VariationySensitivit =
Offtake Structure sensitivity
The discharge sensitivity to water depth at any structure is
defined as the ratio of the relative variation of discharge
through the structure (Q/Q) and water depth deviation
(H) upstream of the structure.
H
S
=
Example: A sensitivity indicator of ‘1 ’ indicates that a
change of 0.1 m in water level in the parent canal generates a
discharge variation (q) through the structure of 0.1 or 10%.
Unit = m-1
q/q
H
SENSITIVITY
• By design sensitivity of offtake is low
(<1) when canals are run at FSD
• Only tail end offtakes are facing harsh
problems of sensitivity and supply
limitations due to low discharge in
canals.

MASSCOTE STEP 3
PERTURBATIONS
Perturbations analysis:
causes,
magnitudes,
frequency and
options for coping with
PERTURBATIONS
CAUSES:
•Unauthorized off-takes (siphons) and lifting of
water from canal
•Temporary constructed obstructions (walls) to raise
water level at offtake
•lack of proper gate to close offtake.
•Inaccuracy in management
MAGNITUDE:
•It is significant in case of pump operation and
illegal withdrawals from pump sets.
Options to cope with :
1. Share the surplus / deficit equally among the
users.
2.The CRs to be operated
3. Surplus to be stored …option to be explored
PERTURBATIONS MASSCOTE STEP 4

STEP 6: SERVICES and VISION
• : Flexibility in main canal discharges
(+5 - 10% depending on discharge)
• Flexibility in 2nd level canals (+20% of discharge)
• Reliability: highly reliable during rabi, varied
reliability during kharif
• Equity: equity during rabi and less equity in kharif
due to system constraints (delayed response during
rains)
• Cost: high cost (Rs 2130/ha)

MASSCOTE STEP 8
MAPPING the DEMAND for OPERATION
Water management strategy:
Kharif:
•Main canal: Continuous flow, tolerance: +/-5%, flow varied during rain fall
•Distributary: Within the Distry Rotation to 3rd level canal, tolerance: +/-10%
•In lift schemes main canal should be used for storing water as buffer storage
(online) to combat voltage fluctuation and also, preferably within CA buffer
storage during rains for optimum utilization of water and as a energy saving
technique.
Rabi:
•Main canal: Continuous flow, tolerance: +/-5%
•Distributary: Within the Distry Rotation to 3rd level canal, tolerance: +/-10%
•Ensure better service to areas without ground water potential.
•Recycling facilities to be made use of by the users.
•Conjunctive use to be encouraged.
MASSCOTE STEP 8
MAPPING the DEMAND for OPERATION
•Operation strategy:
•Rotation with flexibility : kharif: flexibility in main canal
(discharge varies due to rains)
•Duration : 10 days
•Kharif : Flow controlled by CRs and surplus
Stored in buffer storages / canal
•Rabi :Flexibility in main canal limited to availability
Information system : Manual SCADA, digitization of data
•Operation rules at various levels : Kharif-TOL 10 cm
TOL (H) cm Rabi - TOL 5 cm
Main canal : Khariff: 120 days, Rabi: 90 days
CR operated to maintain Water level at FSD.
•New structures to be added : CRs (mixed) and escapes, duck bill weirs in
Dy
Service strategy:1) Allocation of water to farmers :
• Allocation on volumetric basis to WUAs
• Allocation varies for kharif because of contribution of rain fall
• Allocation for rabi is fixed
•Deficit to be shared equally
2) Schedule of watering: Rotation among distributaries for both kharif and
rabi
3)Deliveries: tolerance of 1 days for rabi and 3 day for kharif
4)Specific rules for services to downstream users:
• Water to be fed from tail end to upwards at the beginning of seasons
• Within the distributary rotational delivery starts from tail end
• It is the responsibility of tail enders not to waste water

VISION
“ A very efficient environmentally sustainable
agriculture oriented towards high value
production and value addition. An overall
reliable cost effective water management
targeting equity in water access, multiple uses
throughout the command areas with high
capacity professionals. Farmers active and
responsible in water resource management
progressively taking over management and cost
recovery with other stakeholders. ”
