Reduction in Live Storage Capacity of a Reservoir Due to Sedimentation Using Satellite Imageries

Abstract

AbstractSedimentation is one of the main factors that reduce the gross storage capacity of a reservoir over the period of time. Live storage capacity can be estimated with the help of satellite imageries. Remote sensing technique gives a synoptic view of a reservoir to estimate sedimentation in live storage zone. In this study, LANDSAT 8 satellite imageries are used to find out the loss of live storage capacity and rate of siltation of a Mula reservoir, Maharashtra, India, for the years 2014 and 2018, respectively. The percentage loss of live storage for the years 2014 and 2018 is 5.15 and 5.5, respectively. Rate of siltation for both the study years is same, i.e. around 310 m3/km2/year, which is good under prevailing conditions of Indian reservoirs. The Mula reservoir has not much significant sedimentation issue.KeywordsSedimentationSatellite imageriesLANDSAT 8Mula reservoirLive storage capacityElevation capacity curve
