WMS:Quick Tour -HEC-RAS

The 1D Hydraulic tools in WMS can be used to set up a HEC-RAS GIS Import file. Using feature arcs and polygons, users create a River schematic that consists of a river centerline, which includes data for cross-sections, river reaches, and Manning's roughness coefficients.

Then, using the water surface elevations computed by HEC-RAS, WMS can delineate a floodplain based on ground elevations contained in a TIN.
