Bridge elevation (Water Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	INCLUDE_BRIDGE_ELEVATION	boolean		Whether to include bridges in the elevation model used for the water calculations.	n/a

This attribute defines whether to include bridges and other floating buildings in the elevation model used for the water calculations.

Notes

• This attribute is by default set to 0 which means bridges are not included so water can flow under the bridge.
• In the advanced settings step of the Water Overlay Wizard, this attribute can also be (de)activated.
• For more control, set this attribute to 1 and use asquare culvert to regulate water flowing under a bridge.
