What is Slope Area method?

Slope Area method is computed on the basis of a uniform flow equation involving channel characteristics, water surface profile and a roughness coefficient. The drop in water surface profile for a uniform reach of channel represents losses caused by bed roughness.

What is Non-Uniform Flow?

Flow is said to be non-uniform, when there is a change in the velocity of the flow at different points in a flowing fluid, for a given time. For example, the flow of liquids under pressure through long pipelines of varying diameters is referred to as non-uniform flow.
