Hello, I have a model in HEC-Ras version 5.0.3 that I set-up in Civil 3D 2017 (stream alignment, cross sections, LOB, ROB) and I was asked to add in the Manning roughness values from SRH2D. I was asked to do this because I was told that the .geo file from WMS brings in all of the n-values along the cross section, creating a more real-world HEC-Ras model. Currently, I have only 3 n-values. I found a forum that displayed how to correctly transfer the materials file from SRH2D to WMS, and then create essentially the geometry file in WMS to export to HEC-Ras, but I already did most of this in Civil 3D. I don't want to re-do my .geo file in HEC-Ras because it is basically complete. Is there a way to import only the n-values from SRH2D without re-doing my entire HEC-Ras model created from Civil 3D? Thank you
Does anyone know a process for exporting a materials coverage from SMS to WMS? I would like to use a 2-D materials coverage to define Manning's roughness values in a HEC-RAS model I am preparing in WMS 10.1. Thanks!
