WebGradually Varied Flow Equation For nonuniform open-channel flow, the cross sectional area, depth, and velocity vary along the channel. The flow is classified as gradually … 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 …
WebRapidly Varied Flow. If water depth or velocity change abruptly over a short distance and the pressure distribution is not hydrostatic, the water surface profile is characterized as Rapidly Varying Flow (RVF). The occurrence of RVF is usually a local phenomenon. RVF can often be observed near the inlet and outlet of culverts, and wherever ... WebExplanation: Gradually varied flow is steady non-uniform because the velocity of water remains constant at a specified point, but it changes from one point to another point. The terms steady and uniform are used frequently in engineering, and thus it is important to have a clear understanding of their meanings.
