WebStormwater Open Channels . September 13, 2024 3 Channel slopes vary due to existing topography and the design requirements of each storm drainage system. The desirable minimum slope for open channels is 0.5 percent (.005 ft/ft). In areas of flat topography, the desirable 0.5 percent minimum slope is not always possible to achieve. WebDifferential Equation of GVF. ⇒ Consider the total energy H of a gradually varied flow in a channel of small slope and α = 1.0 as. H= Z + E. H= Z +y + v2/2g. where E = specific energy, v= Q/A. ⇒ In general the water surface varies in the longitudinal (x) direction, the depth of flow and total energy are functions of x. defender arcade game free download
