Also known as WBMplus
Model type Modular
Model part of larger framework
Incorporated models or components:
Spatial dimensions 2D
Spatial extent Global
Model domain Hydrology, Terrestrial
One-line model description Water Balance/Transport Model
Extended model description Gridded water balance model using climate input forcings that calculate surface and subsurface runoff and ground water recharge for each grid cell. The surface and subsurface runoff is propagated horizontally along a prescribed gridded network using Musking type horizontal transport.

Memory requirements --
Typical run time --

Describe input parameters depending on configuration, the model can be run with Air temperature and Precipitation only. In the most complex configuration, the model will also need vapor pressure, solar radiation, wind, daily minimum and maximum temperature. Built-in functions allow trading input variables (e.g. use cloud cover instead of solar radiation).
Input format Binary
Other input format
Describe output parameters The model can output any variables used for the water balance and transport calculations. The most frequently requested ones are: potential and actual evapotranspiration, soil moisture, groundwater storage, river discharge, irrigational water uptake.
