Critical flow occurs when the velocity of water is the same as the speed at which disturbances of the free surface will move through shallow water.

Open channel flow occurs where ever the flow proceeds with the liquid surface exposed to constant pressure. In practice this pressure is the atmospheric ...

Open channel flows are flows in rivers, streams, artificial channels, irrigation ditches, partially filled pipe etc. ◇ Basically, it is a flow with free surface ...

When Fr > 1, the flow possesses a relatively high velocity and shallow depth; on the other hand, when Fr < 1, the velocity is relatively low and the depth is ...

The velocity distribution in a channel section can be measured either by a pitot tube or a currentmeter. The typical patterns of velocity distribution.

Compared to pipe flows, open-channel flows have one more degree of freedom as a result of the free surface. There are essentially two types of open-channel flow ...

UNIT-I- Open Channel Flow. Introduction to Open Channel Flow-Comparison between open channel flow and pipe flow, geometrical parameters of a channel, ...

Open channel flow, like any topic of engineering interest, is defined and classified partly by its possession of certain characteristic applications and partly ...

Normal Depth: For a given channel geometry, slope, and roughness, and a specified value of discharge Q, a unique value of depth occurs in a steady uniform flow.

The most common method of classifying open-channel flows is by the rate of change of the free-surface depth. The simplest and most widely analyzed case is ...
