  1. I tried to run a steady flow through my model in HEC RAS. I get the error 'Station and elevation data contains duplicate points - The cross section filter can be used to remove duplicate points' These extra points can be deleted manually, but it takes awhile and I can't seem to find this "Points Filter" function in HEC RAS. If anyone knows please give me heads up. Thanks
  2. When do you enter the bridge/culvert data? In WMS or in HEC RAS after you go HEC RAS | Export GIS File...
  3. 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? roughness.doc
