Gradually varied flow analysis

WebAbstractThe depths for a steady, gradually varied flow in a rectangular open channel with infinite widthobtained analytically by the Bresse formula and numerically using trapezoidal rule for integration havebeen compared. It has been shown that numerical integration may generate significant errors of flowvalues for looped river networks. WebVaried flow can be further classified as either rapidly or gradually-varied: Rapidly-varied flow The depth changes abruptly over a comparatively short distance. Rapidly varied …
