Use WWHM-SWMM with HEC-RAS Easily

You can now export data from WWHM4 and read it in a Hydrologic Engineering Center's River Analysis System (HEC-RAS) .DSS file.

Simply run HEC-RAS using the unsteady state method and read from the .HYD file. You can even transfer the long-term dataset directly into WWHM4.
