WATER_MANNING | s/(m1/3) | Surface | The Gauckler–Manning coefficient of the terrain |
Terrains 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 values for this attribute are derived from online accessible databases[1] and are readily adjusted by the user.
- If a construction is present on the terrain, the WATER_MANNING value of the construction is used instead.
- Only terrains of type 'surface' have an assigned WATER_MANNING.
