Not AvailableAn attempt was made to estimate the geomorphological degradation due to sedimentation of
Sarda Sagar reservoir, located in Pilibhit and Udhamsingh Nagar, district of Uttar Pradash and
Uttarakhand respectively. The study was conducted using multidated IRS LIISS III remote sensing
data for the year 20062007. Using satellite images of different seasons during 20062007, a total
of 45.23 million m3
volume of sedimentation was computed inbetween the 183.704 m and 190.504
m elevation. The reservoir has lost 11.72 % of the total capacity of water storage and an average
rate of sedimentation was calculated as 0.26 % per year. Due to this sedimentation the new feeder
channel of Sarda Sagar is choked with silt and the water flow from this channel has almost stopped.
The morphology of the reservoir has been changed due to sedimentation during the period 1962 to
2007. This has altered breeding ground of fishes since important indigenous fish species which
need flowing water condition to perform the breeding. This study would be helpful for the planners
to manage the reservoir and to assess the biological productivityNot Availabl
