The sedimentation process is the most important problem that affect directly the performance of reservoirs
due to the reduction of the storage capacity and possible problems affecting the operation. Thus periodic assessment of
the storage capacity and determining sediment deposition patterns is an important issue for operation and management
of reservoirs. In this paper efforts are made to explore the Satellite Remote Sensing (SRS) method for assessment of
reservoir sedimentation at Ajwa Reservoir. It uses the fact that the water spread area of reservoir at various elevations
keeps on decreasing due to sedimentation. Remote Sensing technique gives us directly the water- spread area of the
reservoir at a particular elevation on the date of pass of the satellite. This can help to estimate sedimentation over a
period of time
