Scs lag method

Webb29 jan. 2024 · SCS and Green-Ampt models were coupled to a lag and route model at the cell scale, to produce a cell-hydrograph at the outlet of the catchment, calculated by: (5) where A was the cell-area [L 2 ], Pe the effective rainfall [L], Tm the routing time [T]), and Km the lag time [T] from the cell m to the outlet. Webb6 nov. 2024 · In other words, lag time is a delay in time, after a brief rain over a watershed, before the runoff reaches its peak. The lag time can either be specified by the user, or can be calculated by the model using the following SCS equation. where tl = lag time of the watershed (hr). L = hydraulic length of the watershed (ft).
