Limit area model attribute (Water Overlay)

Icon	Attribute	Unit	Range	Description	Default value
File:Waterwizard icon	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.
