Importing a HEC-1 Model in HEC-HMS

The Import HEC-1 Project command allows a preexisting HEC-1 data file to be imported and converted into a HEC-HMS model, and then displayed on the Map View.

Follow the steps given below to use the Import HEC-1 Project command:

From the Input ribbon menu, click the Import Data menu item and choose the Import HEC-1 Project command.
The Import HEC-1 Project dialog box will be displayed.

The below sections describe the Import HEC-1 Project command and how to interact with the above dialog box.

Selecting HEC-1 Data Files

This section allows the user to select a HEC-1 data file and a DSS file to be imported. The following options are provided:

HEC-1 data file: This field is used to select the HEC-1 data file to import. Clicking on the […] browse button displays the Import HEC-1 Project File dialog box. The user can select the HEC-1 data file. After selecting the file, the user will be returned to the Import HEC-1 Project dialog box, and the complete directory path and the file name will be shown in the HEC-1 data file field.
Associated DSS file: If the HEC-1 file includes ZR records for loading time-series data from a HEC-DSS file, then the user should specify the DSS file that contains the data. Clicking on the […] browse button displays the Import HEC DSS File dialog box. The user can select the DSS file. After selecting the file, the user will be returned to the Import HEC-1 Project dialog box, and the complete directory path and the file name will be shown in the Associated DSS file field.
Note that without specifying the file, the user will have to manually connect to the time-series data.

Defining Associated HEC-HMS Component Names

This section allows the user to enter the name of the basin model, meteorologic model, and control specifications imported from the HEC-1 model.

Importing a HEC-1 Model

Once the user has specified the HEC-1 file name to import, and the names of the three components, click the [Import] button. The software will read the HEC-1 file and create the appropriate parts of the three components.
