Surcharged flow
WebOct 18, 2024 · The surcharge ratio coefficient defines the relationship between headloss and the depth of flow in the pipe: Surcharge ratio = flow depth / conduit height (4) Flow depth is defined as the level in the node, minus the invert level of the pipe (immediately up or downstream of it.) WebDec 1, 2001 · This last equation implies that the water depths upstream and downstream of the pipe are equal. This simplification is valid if variations in the hydrograph are gradual enough to result in a quasi-steady flow for each time step (Motiee et al., 1996) and if the pipe is not surcharged.The water surface is then represented as in Fig. 1.Flow and water depth …
