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 ... http://www.ce.memphis.edu/3180/PDFsF12/Gradually%20Varied%20Flow.pdf inclination\\u0027s 98 https://ypaymoresigns.com
