What is stilling basin?

A stilling basin is a hydraulic structure designed to reduce the energy and turbulence of water flowing from a spillway or dam into a downstream channel. It typically features a wide, flat area that allows water to slow down and settle, preventing erosion and sediment transport. By dissipating energy, stilling basins help maintain the stability of the riverbed and surrounding environment. They are essential for protecting infrastructure and ensuring safe water flow downstream.
