Evaporation

You can include evaporation in your simulation in two different ways. If your simulation does not include any density variations you can include evapora­tion as a negative precipitation (see Precipitation ). If your simulation on the other hand include density variations (or more precisely, temperature variations) you should select the heat exchange option (see Heat Exchange). This implies that the evaporation rate is calculated as a function of the latent heat flux.

You may specify the evaporation rate (as a negative precipitation in mm/day) in one of the following three ways: a constant, from a type 0 data file, or from a type 2 data file.

See the Precipitation description for more details.
