Bridge elevation (Water Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	BRIDGE_ELEVATION	nominal		Specifies the mode by which bridges are include in the elevation model, used for the water calculations.	n/a

0.	Lowest: The lowest terrain height under or near the bridge is used.
1.	Terrain: Bridges are excluded from the DEM, allowed water to flow as if they didn't exist.
2.	Bridge: Bridges and floating Constructions are included in the DEM, blocking water flow.
