Gradually Varied Flow- Open Channel Flow (Chapter-4)

WebUnder steady state flow conditions (e.g. no flood wave), open channel flow can be subdivided into three types of flow: uniform flow, gradually varying flow, and rapidly varying flow. Uniform flow describes a situation where … WebThe calculated gradually varied flow depth varies between the specified flow depth at the upstream boundary [or, if requested, the calculated normal depth for the upstream channel] and [the flow depth increases toward] critical depth downstream. Input WebVaried flow technically may be either steady or unsteady. Varied flow can be further classified as either rapidly or gradually-varied: Rapidly-varied flow. The depth changes abruptly over a comparatively short distance. … irish links courses
