Design flood elevation m (Water Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	DESIGN_FLOOD_ELEVATION_M	m		Buildings in the model are assumed to have at most this height compared to the surface of the terrain. Greater values can create a more accurate model but will impact performance.	1

Notes

• Only values greater than or equal to 0 are permitted. Negative values will lead to undefined behavior.
• To lower the height of Buildings below the normal terrain height, a terrain elevation prequel should be used instead.
