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:

  1. 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
