Evaporation

In applications where the evaporation is important, you can include evapora­tion in your simulation.

This is done either as a constant value or as a time series (type 0 data file), which then is applied to the entire model area, or as a time series of maps (type 2 data file) in which case each grid point is assigned its own value. The evaporation rate is specified in mm/day.

·         You can include evaporation in your simulation in three different ways.

·         If your simulation does not include any density variations you can include evaporation by specifying the evaporation rate in the Source and Sink dialog.

·         You can also use the precipitation facility to include evaporation in your simulation. This is simply done by selecting the “included as net-precipi­tation” option and specifying a negative precipitation. See the Precipita­tion (p. 122) description for more details.
