GeoHECHMS is a data wrapper to the HEC-HMS software. It is quite easy to export the HEC‑HMS project that the software generates. The Export HEC-HMS Project command allows a HEC-HMS project to be exported to HEC-HMS input data files. This allows the HEC-HMS project to be used with the US Army Corps HEC-HMS software.
Follow the steps below to export a HEC‑HMS project:
- From the Input ribbon menu, select the Export Data dropdown menu and then choose the Export HEC-HMS Project command.
- The Export HEC-HMS Project dialog box will be displayed.
The following sections describe the Export HEC-HMS Project command and how to interact with the above dialog box.
