WebIf flow is gradually varied, the depth y and other flow factors vary smoothly from section to another. In varied flow, depth y and other flow factors change abruptly over a very short distance. Discontinuity of flow is also possible. Rapidly varied flow can be seen e.g. at a weir, at a change in channel width, at an hydraulic jump or an ...
