The Soil-Water-Balance (SWB) model has been developed by USGS to allow estimates of potential recharge to be made quickly and easily.
Required Input
Four gridded datasets are required:
- Hydrologic soil group
- land-use/land cover
- Available soil-water capacity
- Surface-water flow direction
In addition to gridded land-surface data the model requires tabular daily climatological data (daily precip (inches), average air temperature [F], max air temp [F], min air temp [F]). Additional data may be required depending on model options: (1) daily average wind speed (m/s), (2) daily average relative humidity (%), (3) daily max relative humidity (%), (4) daily percentage of possible sunshine (%). Finally a lookup table must be supplied to assign curve numbers, interception values, rooting depths, and maximum daily recharge values.
Creating an SWB Simulation
To create an SWB simulation, do the following:
- Right-click in an empty space in the Project Explorer and select New Simulation | SWB.
Simulation Menu
Right-clicking on the simulation item in the Project Explorer will bring up the following menu command:
- Delete
- Duplicate
- Rename
- Model Control
- Model Check
- Export SWB
- Launch SWB
- Save, Export, and Launch SWB
- Properties
Model Control
The parameters for the SWB model run are set in the Model Control dialog.
