Hydraulic engineering is an engineering built for controlling and allocating surface water and underground water in nature to achieve the purposes of removing harmful substances and benefiting. Also known as water engineering. Water is a valuable resource essential for human production and life, but its naturally occurring state does not completely meet the needs of human beings. Only when hydraulic engineering is built, water flow can be controlled, flood disasters are prevented, and water quantity is adjusted and distributed to meet the requirements of people on water resources in life and production. Hydraulic engineering needs to build various types of hydraulic buildings such as dams, dikes, spillways, water gates, water inlets, channels, transition troughs, rafts, fishways and the like so as to achieve the aims.

The energy dissipater is an engineering facility which is built by eliminating the redundant kinetic energy of the water discharge building or the downward discharge torrent of the drop building and preventing or reducing the scouring damage of water flow to the hydraulic building and the downstream canal thereof. Hydropower stations built in the middle and downstream of rivers are often limited by the landform conditions of dam sites and the flood discharge overflow width. The single width flow of the flood discharge gate is large, the water head is relatively low, and the conditions make the flood discharge energy dissipation problem become one of the control factors of the project hub arrangement. The energy dissipater is required to relieve pressure, so that the engineering facilities built by scouring and damaging the hydraulic buildings, downstream rivers, channels and the like by water flow are prevented or reduced.
