George Mason University CEIE 442 Open Channel Flow Slope 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 ...

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 ...
