Gradually varied flow ppt
WebA gradually varied flow (GVF) profile is a plot of water depth versus distance along the channel as the water depth gradually achieves normal depth. A GVF computation in a trapezoidal channel involves starting at a known depth Y s and making successive water depth computations at small distance intervals. The method involves the continuity ... Webvelocity of the flow is constant with distance. Gradually varied flow. Depth of flow changes gradually with distance. Acceleration and deceleration of flow is neglected. Only. viscous forces are considered. Rapidly varied flow. Considerable flow depth changes within a short distance. Viscous forces are neglected and inertial forces are.

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.
