Water manning (Water Overlay)

Manning's n (construction)

Constructions 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 default function values are derived from online accessible databases and are readily adjustable by the user.
• If no constructions are present on a terrain, the WATER_MANNING value of the surface terrain is used.

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