A dousing basin is a basin located below the actual weir body (weir). There is an energy potential between the upper and lower water of a dam, which must be converted below the weir in such a way that scouring (scour) in the water bed and damage to the structure by the flowing water are avoided. Under certain circumstances, supported by interference bodies (bumps, tooth sill), an alternating jump is generated. The shooting drain, as it passes over the weir, turns into a flowing drain. The kinetic energy of the flowing water is converted into heat and sound energy in the resulting top roller. Depending on the depth of water in the underwater of the damming system, there may also be a corrugated change in which the energy conversion extends over a larger area in the underwater.
