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.

Slope protection refers to the general term of various paving and planting on a slope surface in order to prevent the slope from being washed.
