The hydraulic jump basin is often favored by designers since it has been extensively studied and is well documented. A properly designed basin can usually dissipate 50 to 70 percent of the energy in the flow within the basin. Tailwater is required for successful operation..."

Special design considerations are necessary for dams with downstream control. A common recommendation is to house the conduit in a concrete-lined tunnel or to encase the conduit in concrete. Outlet facilities with downstream con..."
