Unsteady flow also called ‘Transient Flow’, occurs in the open channel when the discharge or depth or both vary with respect to time at a given section.

In Rapidly Varied Flow (R.V.F), a sudden change of depth occurs at a particular point of a channel and the change from one depth to another takes place at a distance of very short length.

The gradually varied flow (GVF) is defined as steady non- uniform flow, where the depth of flow varies gradually from section to section along the length of channel. (A steady non-uniform flow in a prismatic channel with gradual changes in its water surface elevation is termed as gradually varied flow (GVF).

A flow in an open channel is said to be uniform if its properties remain constant with respect to space. Detailed discussion about Uniform Flow.
Open channel flow refers to the flow of liquid in channel open to atmosphere or in partially filled conduit (Pipe). Example- River, Flood, Rivulets, Torrent, Sewers carrying sewage, Rode side Gutter. Detailed discuss about OCF.
