Limit rain (Water Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	LIMIT_RAIN	nominal value		Whether rainfall can be overridden 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.
• Override specified Areas The weather's configured rainfall can be overridden by rain areas' Rain M attribute.

Possible values

• 0: Entire map
• 3: Override Areas

Notes

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