WebKinematic Wave Routing - Example. The inflow hydrograph to a rectangular channel is tabulated below. The channel has a width of 100 ft, a bottom slope of 0.001, and Manning n of 0.035. The length of the channel is L = 25000 ft. ... For each value of discharge, determine the corresponding flow depth by solving Manning equation: Flood routing is a procedure to determine the time and magnitude of flow (i.e., the flow hydrograph) at a point on a watercourse from known or assumed hydrographs at one or more points upstream. The procedure is specifically known as Flood routing, if the flow is a flood. After Routing, the peak gets attenuated & a time lag is introduced. In order to determine the change in shape of a hydrograph of a flood as it travels through a natural river or artificial channel, differen…
