The default value for the WATER_MANNING attribute of surface type "Open land". The user can change this value.
Icon Attribute Unit Layer Range Description
Waterwizard icon manning.png 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.
