===Manning value (construction)===
[[Construction]]s have an inherent "roughness", which influences how fast water can flow across the surface. This is known as the Manning coefficient or Manning value.


===Notes===
[[Building]]s 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'').
* If no construction is present in any location, the [[Terrain water manning (Water Overlay)|WATER_MANNING]] value of the surface terrain present is used instead.

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) 0.01 to 0.255 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 manning value can alternatively be provided as a prequel.
  • The default function values are derived from online accessible databases[1] 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.
