WebMar 29, 2024 · Figure 6.2 Illustration of Storage Effects on Flood Hydrographs. Most runoff routing model utilises a simple storage routing algorithm based on the continuity equation and a storage equation of the general form S = kQ m. The storage equation is non-linear and this form of the storage equation is justifiable by both theoretical and empirical means. 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…
