George Mason University CEIE 442 Open Channel Flow Slope WebSteady, gradually varied flow is discussed in this chapter and the rapidly varied flow in Chapter 7. The gradually varied flow equations are first derived. The classification of various water surface profiles is then presented. This is followed by a presentation of procedures for qualitatively sketching the water-surface profiles and for ...

WebThe primary procedure used by HEC-RAS to compute water surface profiles assumes a steady, gradually varied flow scenario, and is called the direct step method. The basic computational procedure is based on an iterative solution of the energy equation: , which states that the total energy (H) at any given location along the stream is the sum of ... 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 ...
