Materials¶
In MIKE+, a link may be characterised by material, which determines the Manning friction coefficient (Manning), the Colebrook-White coefficient (EQ Roughness), or Hazen-Williams coefficient (H-W Coefficient) for the conduit. It is optional to use either the default roughness values for specific materials or local values.
Specification of the different kind of materials and roughness coefficients is done through the Materials editor.

MIKE+ has the following pre-defined Material types with friction loss properties:
- Cement Mortar
- Ceramics
- Concrete (Normal)
- Concrete (Rough)
- Concrete (Smooth)
- Iron (cast)
- Iron (wrought)
- Plastic
- Stone.
