In hydrology, routing is a technique used to predict the changes in shape of a hydrograph as water moves through a river channel or a reservoir. In flood forecasting, hydrologists may want to know how a short burst of intense rain in an area upstream of a city will change as it reaches the city. … Zobacz więcej Hydraulic routing is based on the solution of partial differential equations of unsteady open-channel flow. The equations used are the Saint-Venant equations or the associated dynamic wave equations. The hydraulic … Zobacz więcej 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 … Zobacz więcej • Hydrograph • One-dimensional Saint-Venant equations Zobacz więcej Hydrologic routing uses the continuity equation for hydrology.
