===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.

====Manning's ''n'' (construction)====
* If no construction is present in a location, the [[Terrain water manning (Water Overlay)|WATER_MANNING]] value of the surface terrain in that location is used instead.
[[Construction]]s have an inherent "roughness", affecting the flow of water across its surface, which is expressed by the Gauckler–Manning coefficient or, in short, Manning's value (''n'').

Manning's n (construction)

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

Notes

  • The default function values are derived from online accessible databases[1] and are not adjustable.
  • If no construction is present on the terrain, the WATER_MANNING value of the surface terrain is used instead.

The default function values for a number of constructions. The user cannot change these values.
