Abstract
The study was undertaken to evaluate performance of Bhimsagar Irrigation Project
(BIP). The three minors each located on Left and Right Main Canal were selected for
evaluation study. Performance was evaluated using different performance indicators which
include - Water delivery performance indicators, Technical performance indicators,
Maintenance and Comparative performance indicators.
The physical state of canal distribution system was found to be poor. The gates and
pipe outlets were found damaged at 18 places. Excessive vegetation/weed growth was
observed in the canals. Silt deposition was observed at 15 places in main canals/minors. Due
to excess seepage from canal, water logging problem is observed in pockets of command area.
Soybean and Wheat are the major crops of Kharif and Rabi season respectively.
The overall adequacy for Bhimsagar irrigation project was found fair for head and
middle reaches whereas ‘poor’ adequacy was found for tail reaches. The average gates
adequacy was found
‘poor’ with value 0.765. The system was found unreliable in water delivery with respect to
time with average dependability value of 0.498 due to faulty water distribution methods.
Overall equity was found good to fair at head and middle reaches whereas poor at tail reaches
due to unfair share of water from head to tail reaches.
Average water storage efficiency was found as 85.35. Area uniformity was found as
poor due to unfair share of water from head to tail reaches. Average on farm application
efficiency was found as 79.40 per cent indicating water is applied efficiently to the land.
Water conveyance efficiency was found as 75.26 per cent, which indicates almost 25 per cent
water is lost during conveyance. Wheat crop was found most efficient in terms of water
utilization. Water Use efficiency of Rabi crops was found maximum in year 2013-14.
Average relative change of water level was observed between 11-13 per cent,
showing water level was decreased in the canal from the designed level. Effectiveness of
infrastructure was 82 per cent which means 18 per cent structures are damaged.
Output per unit of land cropped and Output per unit of command area was found
maximum in year 2013-14 and minimum in year 2009-10. Output per unit of irrigation supply
was found highest in 2010-11 whereas Output per unit of water consumed was found highest
in year 2012-13. Average values of relative water supply and relative irrigation supply was
found inadequate at tail reaches of canals in the year 2013-14. The irrigation ratio was found
‘poor’. Canal Network was found sustainable from years 2011-12 to 2013-14 by obtaining
sustainability of irrigated area value of higher than 100 per cent. Area infrastructure ratio were
more than projected value of 108.46 Km/ha from 2011-12 to 2013-14. Average of gross
return on investment was found as 21.44 per cent. Financial self-sufficiency of project is on
decreasing path from year 2006-07 (except 2010-11) and observed minimum (54 per cent) in
year 2013-14 on account of increasing in O&M expenditure.
