Exporting a HEC-RAS Model - CivilGEO Knowledge Base

GeoHECRAS is a data wrapper to the HEC‑RAS software. It is quite easy to export the HEC‑RAS project that the software generates. The Export HEC-RAS Project command allows a HEC-RAS river model to be exported to external HEC-RAS files. This allows the HEC-RAS project to be used with the US Army Corps HEC-RAS software.

Follow the steps below to export a HEC‑RAS project:

From the Input ribbon menu, click the Export Data dropdown menu and then select the Export HEC‑RAS Project command.
The Export HEC‑RAS Project dialog box will be displayed.

The following sections describe the Export HEC-RAS Project command and how to interact with the above dialog box.

Selecting HEC-RAS File Type to Export

The Select HEC-RAS File Type to Export section allows the user to select the HEC-RAS file type to export. The following options are provided:

HEC-RAS input data files: Selecting this radio button option allows the user to export out the standard HEC-RAS input data files, including the project file, plan files, geometry files, steady flow files, and unsteady flow files. Clicking on the […] browse button displays the Export HEC-RAS Input Data Files dialog box where the available file types are “HEC-RAS Project Files (*.prj)”. After the user defines the HEC-RAS file name, the complete directory path and HEC-RAS project file name is shown in the adjacent string field.
HEC-RAS archive (ZIP) file: Selecting this radio button option allows the user to archive all of the standard HEC-RAS input data files (project file, plan files, geometry files, steady flow files, and unsteady flow files) into a single archive ZIP file. Clicking on the […] browse button displays the Export HEC-RAS Archive (ZIP) File dialog box where the available file types are “Archive File (*.zip)”. After the user defines the archive file name, the complete directory path and ZIP file name is shown in the adjacent string field.

Exporting Options

The Export Options section allows the user to select the specific HEC-RAS data to export. The following options are provided:

Include output results with HEC-RAS archive: Selecting this option allows the user to include the HEC-RAS model analysis output files in the archive ZIP file.
Include all support files (i.e., terrain, land cover) with HEC-RAS archive: Selecting this option allows the user to include terrain, land cover, etc., in the ZIP file.
Include base map layer: Selecting this option allows the user to include the background base map as a georeferenced JPG image file.

Selecting Scenarios (Plans) to Export

The Select Scenarios (Plans) to Export section contains a radio button group that controls what plan data from the current HEC-RAS project file is to be exported. The following options are provided:

All scenarios: Selecting this radio button option causes all scenarios (or plans) contained within the current HEC-RAS project to be exported to equivalent scenarios.
Select scenario: Selecting this radio button option allows the user to select a single scenario (or plan) contained within the current HEC-RAS project to be exported to an equivalent scenario.
