Web17. Uniform and non-uniform Flows. If the flow properties, say the depth of. flow, in an open channel remain constant along. the length of channel, the flow is said to be. uniform. As a corollary of this, a flow in which. the flow properties vary along the channel is. termed as non-uniform flow or varied flow.
