Abstract:
The hydro-geologic processes like erosion, movement and deposition of sediment play a significant role in the planning of reservoir projects. Reservoir silting is an important factor on which depends the life of the reservoir and the long term benefits from the stored water for various purposes viz., domestic water supply, irrigation, power, flood control and other uses. Capacity surveys of reservoirs at regular intervals are considered necessary to evaluate their useful life as well as to assist in optimal reservoir operation. The hydrographic surveys through conventional methods are laborious, time consuming and prone to errors. Remote sensing technique has emerged and established itself as a useful cost effective and efficient tool to estimate capacity loss in reservoir at frequent intervals. This has been demonstrated by a case study in the present paper
