Running HEC RAS in WMS

Recommended Posts

I have a centerline coverage and a cross section coverage along with a TIN. I'm trying to define roughness values for the model. I have created materials in Edit | Material Data and entered roughness values in HEC-RAS | Material Properties.... when I go into HEC-RAS | Model Control there is no option to select 'Materials' for use in generating roughness values. Do I need to build polygons and creat a new coverage for the roughness values?

Sheamus,

You'll want to create polygons on an area property coverage. Once you build polygons, you can double click on each polygon and assign it a material. Like you said, in the HEC-RAs Material properties window, you can associate a roughness value with each material. So then when you extract cross-sections, line properties will be generated from the Area Property coverage. Once you do this, you should be able to select "Materials" from the Model Control drop down box.
