Definition

Hydraulic Engineering is a sub-discipline of ‘Civil Engineering’ concerned with the flow and conveyance of fluids, principally water. This area of engineering is intimately related to the design of bridges, dams, channels, canals, and levess and to both sanitary and environmental engineering.

Common topics for design of Hydraulic Engineers are: Hydraulic Structures like dams, levees, culverts; Water Distribution networks, water collection networks, storm water management, sediment transport and various other topics related to Transportation Engineering and Geotechnical Engineering
