Impact flood threshold m (Water Overlay)

The impact flood threshold 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_FLOOD_THRESHOLD_M	m		The amount of water a Building must experience before it is considered impacted by water.	0,1

Water must reach this height either on one of the cells the Building is on, or on one of the cells adjacent to it. With the impact range m attribute the width of the water along the facade can be adjusted. This is used to compute the Impacted buildings result type.

• 

  Water Overlay with a configured flood threshold of 0.1m and a impact range of 3m.

• 

  Water Overlay with a configured flood threshold of 0.5m and a impact range of 3m.

• 

  Surface last value result overlay of a 30 minute flood caused by a Breach.

Notes

• The default value for Flooding Overlays is 0,5m.
