Abstract

An 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 2006-2007. Using satellite images of different seasons during 2006-2007, a total of 45.23 million m³ volume of sedimentation was computed in-between 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 productivity.?
