Rainfall-runoff modelling is a first stage of the simulation that creates the runoff time series for the individual catchments. The simulation of the flow in the river branches is performed at a second stage.
· There are several rainfall-runoff models available:
· NAM. A lumped, conceptual rainfall-runoff model, simulating the overland flow, interflow, and baseflow components as a function of the moisture contents in four storages.
· UHM. The Unit Hydrograph Model includes different loss models (constant, proportional) and the SCS method for estimating storm runoff.
Note: The rainfall-runoff tab is available only if the rainfall-runoff module is activated in the Modules menu (4.1.1) and if a rainfall-runoff model has been selected for the catchment in the General tab.
