The default function values for a number of constructions. The user can easily change these values.
Icon Attribute Unit Range Description
Waterwizard icon manning.png WATER_MANNING s/(m1/3) The Gauckler–Manning coefficient of the 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 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.
