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.
