Abstract: Reservoirs are the storage of large amounts of water, typically utilized for irrigation, drinking purposes, hydropower generation, etc. Sedimentation is the threat to the life of the reservoir through the accumulation of sediment particles. Reservoir sedimentation poses a significant challenge to the storage capacity, longevity, and functionality of the reservoir. Traditional knowledge for estimating reservoir storage capacity and sediment volume, including inflow-outflow methods, hydrographic surveys, and integrated bathymetric surveys requires more time, cost, and labour. This study aims to employ LISS-III sensor satellite imagery and GIS approach to investigate sedimentation in the Barna reservoir, addressing the limitations of traditional approaches. The analysis indicates that the live storage capacity of Barna reservoir has decreased from 458.54 Mm3 to 395.78 Mm3, resulting in a 13.69% reduction in live storage over the previous 44 years (1975-2019).
