Water manning (Water Overlay)

The default function values for a number of buildings. The user can easily change these values.

Icon	Attribute	Unit	Range	Description
	WATER_MANNING	s/(m1/3)		The Gauckler–Manning coefficient of the building.

Buildings have an inherent "roughness", affecting the flow of water across their surface, which is expressed by the Gauckler–Manning coefficient or, in short, Manning's value (n).

Notes

• The values for this attribute are clamped between 0.01 and 0.255.
• The manning value can alternatively be provided as a prequel.
• The default function values are derived from online accessible databases and are readily adjustable by the user.
• If no Buildings are present on a Terrain, the WATER_MANNING value of the surface terrain is used.
