A Review on Reservoir Sedimentation Studies Using Satellite Remote Sensing Technique

Sedimentation in the reservoir gradually reduces its storage capacity. By keeping a check on the sedimentation and by providing control measures for the same, the reservoir life can be maintained. Ujjani dam was constructed for irrigation, water supply and power generation schemes. It lies in Solapur district which is a drought prone area. This makes Ujjani a socially and economically significant project for the state. In the present study, reservoir sedimentation for Ujjani reservoir is assessed for monitoring purpose. Two techniques namely Satellite Remote Sensing Technique (SRST) and mathematical modeling using HEC RAS, were used in the study for estimating sedimentation. Owing to advantages like low cost, time saving, less manpower requirement, accuracy in estimation and capability of carrying out past surveys, the Satellite Remote Sensing Technique is gaining importance over the time consuming and high cost conventional hydrographic surveys
