摘要

Dams and reservoirs are important infrastructures to conserve soil and water, and saving downstream areas from floods and droughts. At present reservoir sedimentation has become an important issue all over the world. As sediments get accumulated into the reservoir its storage capacity reduces and useful life is shortened. The present study was carried out on Saleran dam reservoir situated in the Hoshiarpur district of Punjab using multi-date satellite imageries of the Landsat 8 OLI sensor. The Modified Normalized Difference Water Index (MNDWI), False Color Composite (FCC) along with the ground truth survey data were used to estimate the reservoir water surface area at different water elevations for different months of the years 2016–2019. The total catchment area of the Saleran reservoir was found to be 749.64 ha and it was observed that the Saleran reservoir has lost 79.67 ha-m (37.36%) in its capacity at a rate of 1.49%, annually due to a siltation rate of 51.65 Mg/ha/yr. So, there is urgent need of conservation measures in dam catchment using check dams, afforestation and contour building to reduce the amount of sediment inflow into the Saleran dam reservoir of Shivailik foot-hills.
