Hydraulic Engineering, which is a branch of civil engineering, mainly focuses on the flow and conveyance of fluids, principally water and sewage. It is related to the design of bridges, channels, canals and dams and its main sub-branches include flood control works, hydraulic and hydro-power engineering, key water-control project, channel regulation project, port engineering, soil and water conservation works, water supply engineering, water drainage works and so on..

As it is an extensive subject, it involves in much specialized vocabulary. To perform well when translating this subject related materials, we should master a lot of technical terms. The following are some terminology frequently used in hydraulic engineering.
