This article is for the HEC-RAS Model. This model is no longer included in SMS. The HEC-RAS model is now part of WMS – Watershed Modeling System.


SMS uses an Area Property coverage to map the roughness line properties to segments of a cross section. The cross sections store the material property ID's and in order for SMS to correctly associate a material ID with an actual roughness they must be defined using the Material Properties dialog.
