Reservoir sedimentation

Reservoir sedimentation occurs when particles like soil, sand, and minerals carried by flowing water settle at the bottom of a reservoir. Over time, these sediments accumulate, reducing the reservoir's water storage capacity and potentially affecting water quality and infrastructure. Sedimentation is mainly caused by upstream erosion, land disturbances, and natural flow dynamics. Managing sedimentation involves methods such as dredging, sediment bypassing, or implementing upstream erosion controls, ensuring reservoirs remain functional and sustainable for water supply, flood control, and hydropower generation.
