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. n/a

There are a few modes available for the Water Module, dictating where calculations are to be performed:

  • Entire map. Calculations are performed across the entire map. Water can flow anywhere.
  • Limit to Water Level Areas Calculations are only performed in the locations where water level areas are present.
  • Limit to specific Areas Calculations are only performed in the locations where limitation areas are present.

Possible values

  • 0: Entire map
  • 1: Limit to Water Level Areas
  • 2: Limit to specific Areas

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 level 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.
