Energy dissipation is the dissipation kinetic energy generated at base of a spillway. While the upstream water is directed to dam downstream, a hydraulic energy flow is created. High velocities occur in the hydraulic energy flow. These high velocities create high pressure and friction forces that cause erosion and scouring in the downstream. As a result, structures could collapse or serious damages could occur. Structures that dissipate the energy levels are high in especially spillways, planning energy dissipators requires great caution and knowledge. When hydraulic energy is dissipated, certain disruptions occur in the flow. The disruptions could cause resonance, erosion, wearing of the surfaces and cavitations. Because of these factors, energy dissipator structures are built. The horizontal apron type of stilling basin energy dissipators are adopted in this project. In order to prevent scouring that occurs when high velocity water enters the downstream of the dam. Vaigai dam is a small village in Periyakulam block in Theni district of TN, India. The dam is in near Andipatti at Periyakulam. The stilling basin is provided at the spillway of the dam. The stilling basins with the drops are given in this project. The project is about designing and estimation of stilling basin with drops at Vaigai Dam. The Plan and Elevation is drawn by using AUTOCAD. The design of stilling basin is done by using IS4997:1968 and the estimation was given at this report.
