Sediment accumulation behind hydroelectric dams leads to several significant environmental impacts, affecting both the reservoir itself and downstream ecosystems. The primary impact is the alteration of the natural sediment transport regime. Dams trap sediment that would normally flow downstream, leading to sediment starvation downstream of the dam. This sediment starvation can cause riverbed erosion, loss of riparian habitat, and reduced nutrient delivery to downstream ecosystems, including deltas and coastal ....
