WebFlow routing is a procedure for determining the time and magnitude of flow {i.e., the flow hydrograph) at a point on a watercourse from known or assumed hydrograph at one or more points upstream. In a broad sense, flow routing may be considered as an analysis to trace the flow through a hydrologic system for a given input. WebInstead of numerically solving the Saint-Venant equations in a coupled manner, as is typically done in unsteady flow-routing, the momentum equation is solved a priori and summarized in the HPGs, which are then used to describe the momentum at each time step. The description of momentum from the HPGs is coupled with the description of continuity ...
