There are a few modes available for the [[Water Module]], dictating where calculations are to be performed:
There are two rainfall modes available for the [[Water Module]]:
* '''Entire map'''. Calculations are performed across the entire map. Water can flow anywhere.
* '''Entire map'''. Only the weather's configured rainfall is used.
* '''Limit to Water Level Areas''' Calculations are only performed in the locations where [[water level area (Water Overlay)|water level area]]s are present.
* '''Limit to specific Areas''' The weather's configured rainfall  can be overriden by [[Rain area (Water Overlay)|rain areas']] [[Rain M (Water Overlay)|Rain M]] attribute.
* '''Limit to specific Areas''' Calculations are only performed in the locations where [[limitation area (Water Overlay)|limitation areas]] are present.

Icon Attribute Unit Range Description Default value
LIMIT_RAIN nominal value Whether rainfall can be overriden by rainfall defined in rain areas across the project area. n/a

There are two rainfall modes available for the Water Module:

  • Entire map. Only the weather's configured rainfall is used.
  • Limit to specific Areas The weather's configured rainfall can be overriden by rain areas' Rain M attribute.

Possible values

  • 0: Entire map
  • 2: Limit to specific Areas

Notes

  • In step 1 of the Water Overlay Wizard, the to be calculated area can be selected. When the option 'Limit to specified areas is chosen', an extra step in the wizard is added.
