Functional unit area should be equal to the maximum irrigated area plus any undeveloped area.
There are four model parameters which are available for calibration and are set up in the main Rainfall Runoff (RR) Model table interface.
Agricultural Runoff Model parameters: Flow routing: Use algorithms for Ts, Tq and SFI parameters in Ihacres
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 |
Beyond the parameters which are set up in the RR table, the Agricultural Rainfall-Runoff model is configured with the same options as those of the Irrigator Demand Model options. The Feature Editor column in the Rainfall Runoff Model table is used to access and configure these.
