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 parameters Ts, Tq and Vs use the same algorithms as the Ts, Tq and SFI parameters in the IHACRES Rainfall Runoff Model.
There are four model parameters which are available for calibration and are set up in the main Rainfall Runoff (RR) Model table interface.

Parameter | Description | Units | Default | Min | Max |
Ts | Time constant governing the rate of recession of slow flow (Ts > Tq) | Time step | 10 | 1 | 100 |
Tq | Time constant governing the rate of recession of quick flow | Time step | 1 | 1 | 10 |
Vs | Proportion of slow flow to total flow | % | 0.5 | 0 | 1 |
| Soil Moisture Capacity | % | 0 |

The relevant Functional Unit area should be equal to the maximum irrigated area plus any undeveloped area.
