For a Water Overlay, evaporation rate is defined in Weather) data.

Editor → Current Situation (Ribbon tab) → Overlays (Ribbon bar) → The Water Overlay (Left panel) → Configuration Wizard (Right panel)

How to set linear evaporation rate:

  1. Open the configuration wizard of the Water Overlay.
  2. Continue to the step concerning weathers.
  3. Select the weather event you wish to update, or select "Add" to create a new one.
  4. Set the "Surface evaporation" setting to "Linear".
  5. In the "Surface evaporation" field, set the desired evaporation rate.
  6. Close the wizard.


The evaporation rate is in mm/day, so for any given evaporation rate configured, the total amount of evaporation will be less as simulation time decreases.
