There are a few modes available for the [[Water Module]], dictating where calculations are to be performed:
{{nominal list|zeroindex=true
* '''Entire map'''. Calculations are performed across the entire map. Water can flow anywhere.
|| '''Entire map''': Calculations are performed across the entire map. Water can flow anywhere.
* '''Limit to Water Areas''' Calculations are only performed in the locations where [[water area (Water Overlay)|water area]]s are present.  
|| '''Limit to Water Areas''': Calculations are only performed in the locations where [[water area (Water Overlay)|water area]]s are present.  
* '''Limit to specific Areas''' Calculations are only performed in the locations where [[limitation area (Water Overlay)|limitation areas]] are present.
|| '''Limit to specific Areas''': Calculations are only performed in the locations where [[limitation area (Water Overlay)|limitation areas]] are present.
 
}}
==Possible values==
* 0: '''Entire map'''
* 1: '''Limit to Water Areas'''
* 2: '''Limit to specific Areas'''

Icon Attribute Unit Range Description Default value
LIMIT_AREA nominal value Whether and how calculations in the simulation should be limited to specific locations of the 3D world. Entire map

0. Entire map: Calculations are performed across the entire map. Water can flow anywhere.
1. Limit to Water Areas: Calculations are only performed in the locations where water areas are present.
2. Limit to specific Areas: Calculations are only performed in the locations where limitation areas are present.

Notes

  • The overlay attribute name for this option is LIMIT_AREA, which is similar to the default Overlay key for Limitation areas.
  • When any limit is in effect, water can flow between valid locations, even if those locations are defined through different relevant features (e.g. 2 adjacent water areas).
  • In step 1 of the Water Overlay Wizard, the to be calculated area can be selected. When chosen for the option Limit to specified areas, an extra step in the wizard is added.
