Gradually varied flow analysis
WebIf the flow depth is changing gradually over a long distance, then flow is Gradually Varied Flow (GVF) and if the flow depth is rapid over a short distance, then the flow is Rapidly … WebGradually varied unsteady flow: Passage of flood wave in a river. Rapidly varied steady flow: A hydraulic jump below a spillway or a sluice gate. Rapidly varied unsteady flow: A surge moving up a canal breaking of wave on the shore. Spatially varied steady flow: Flow over side weir or flow over bottom rock.

The shear stress and the average velocity were obtained from the velocity profile analysis, and a new value of n was computed using Equation (6). The new value was introduced in HEC-RAS to … The energy equation used for open channel flow computations is a simplification of the Bernoulli Equation (See Bernoulli Principle), which takes into account pressure head, elevation head, and velocity head. (Note, energy and head are synonymous in Fluid Dynamics. See Pressure head for more details.) In open channels, it is assumed that changes in atmospheric pressure are negligible, t…
