Impact range m (Water Overlay)

The impact range m setting can be configured in the Output Overlays step of a Water Overlay wizard when the impacted buildings result is selected as an output overlay.

Icon	Attribute	Unit	Range	Description	Default value
	IMPACT_RANGE_M	m		the width in meters of the water next to or against the building that have to be flooded before the building is considered impacted by water.	3

This attribute can tune the amount of cells that has to be flooded before the building is considered impacted. For example a value of 0 means the buildings is always impacted, a value of 1 means at least 1m of cells touching the building needs to be flooded and so on. With the Impact flood threshold m attribute the height of the water can be adjusted.
