12.21EVT Evapotranspiration package

The evapotranspiration package defines the evapotranspiration by plant transpiration or directly from the saturated groundwater by three IDFs: evapotranspiration rate (0.001L/T), top elevation (L) for maximal evapotranspiration rate and thickness (L) over which the evapotranspiration rate is reduced to zero. The EVT package is comparable to the EVT package of MODFLOW. Remember that the units for the evapotranspiration rate are mm/d for iMODFLOW.

The EVT package may be replaced by the CAP module which makes a more sophisticated simulation of the processes in the unsaturated zone.
