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 can be selected. When the option 'Limit to specified areas is chosen', an extra step in the wizard is added.
