Erosion and sedimentation analysis was carried out using the USLE method to determine sedimentation potential based on 2019 land use, reservoir storage capacity analysis using bathymetry results to determine sedimentation rates and prediction of reservoir life, and sediment balance analysis to determine appropriate sediment management efforts. Integrated sediment management from upstream to downstream (reservoir) is a solution. Watershed conservation is the most important effort in sediment management, because watershed conservation can reduce sedimentation potential by 3,16%. Management and construction of sediment control structures on the Brantas River and Lesti River as well as construction of retaining structures and waste processing at the settlement pond location upstream of the Sengguruh Reservoir can reduce reservoir sedimentation
