Also available is the option to add flow routing to return flows, to represent the function of routing parameters in standard rainfall-runoff models. The flow routing model Linear Storage Routing parameters Ts, Tq and Vs use the same algorithms as the Ts, Tq and SFI parameters in the IHACRES Rainfall Runoff Modeldescribed in the IHACRES-CMD - SRG, except that effective rainfall U is replaced with return flow at the point it leaves the water user.
There are four model parameters which are available for calibration and are set up in the main Rainfall Runoff (RR) Model table interface.
