Rainfall-runoff
Webb27 jan. 2024 · The proposed method to identify rainfall-runoff events is based on a time series analysis technique that simultaneously considers rainfall and streamflow time series and does not make any a priori … A runoff model or rainfall-runoff model describes how rainfall is converted into runoff in a drainage basin (catchment area or watershed). More precisely, it produces a surface runoff hydrograph in response to a rainfall event, represented by and input as a hyetograph. Rainfall-runoff models need to be … Visa mer The hydrology of a linear reservoir (figure 1) is governed by two equations. 1. flow equation: Q = A·S, with units [L/T], where L is length (e.g. mm) and T is time (e.g. h, day) 2. continuity or water balance equation: R = Q + … Visa mer The recharge, also called effective rainfall or rainfall excess, can be modeled by a pre-reservoir (figure 6) giving the recharge as overflow. The pre-reservoir knows the following elements: Visa mer Figures 3 and 4 were made with the RainOff program, designed to analyse rainfall and runoff using the non-linear reservoir model with … Visa mer Contrary to the linear reservoir, the non linear reservoir has a reaction factor A that is not a constant, but it is a function of S or Q (figure 2, 3). Normally A increases with Q and S because the higher the water level is the higher the discharge … Visa mer The Nash model uses a series (cascade) of linear reservoirs in which each reservoir empties into the next until the runoff is obtained.
