Hydraulics deals with the study of fluids: their behavior, motion and interaction of fluids with other bodies. Technically fluids include liquids and gases, but from the perspective of Hydraulics in Civil Engineering the term fluid generally means a liquid and water in particular.
Hydraulics includes the study and analysis of fluids when in motion and stationary. The part of Hydraulics which deals with the study of static behavior and interaction of fluids is called as Hydrostatics; the part dealing with fluid in motion is called Hydrodynamics.
In Civil Engineering Hydraulics we study fluid properties and behavior in different civil engineering applications, such as, flow of water through canals for irrigation, flow through public supply pipelines and water drainage system. In Civil Engineering Hydraulics we also study the effect of static fluid, such as, the pressure and force exerted by water stored in dams on its walls.
