SMS:HEC-RAS Material Properties
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.
Assigning Materials
Roughness values for HECRAS are tied to materials in SMS which must be assigned as line properties inside the cross-section database. To assign roughness values to the materials, choose HecRas | Material Properties. Also, the property type that is being used for the material values must be specified in the model control dialog. This dialog is accessed by selecting HecRas | Model Control from the menu.
