In general, it is recommended to store HEC-DSS (and/or gridded) inundation data files in the shared HEC-FIA study directory. The Open browser window closes, and the path to the selected HEC-DSS file populates in the Define Event dialog box, in the DSS File box. dss ) for the hydraulic event of interest, select the HEC-DSS filename (e.g., LeveeSimulation.dss) and click *Open.

Navigate to an existing HEC-DSS dataset (.

The Open browser window opens for HEC-DSS files. From the Define Event dialog box, from the DSS File box, click the button. From the shortcut menu, click Define Event a dialog box opens (based on the inundation configuration type).įor the CCPs Only, Cross Sections Only and Grids and Cross Sections inundation configurations, the Define Event dialog box opens.

From the Study Tree, which is in the Study Pane, from the Inundation Data folder, right-click on the appropriate inundation configuration name.Further, the HEC-DSS file path must coordinate with the A, B, and C parts imported in the CCP, cross section, or storage area set used in the selected watershed configuration (step 2 of the *New Inundation Configuration wizard, review Creating New Inundation Configurations). The user must select a HEC-DSS file path, and a computational output (E part) for inundation configurations (i.e., CCP Only, Cross Sections Only, and Grids and Cross Sections) which require mapping to. HEC-FIA utilizes the A, B and C parts defined by the user at each location to compute a hydraulic event. In a watershed configuration, the user has selected one or more of the following: a reservoir set, a cross section set, a storage area set, or a CCP set (standard or CCPs with holdout distribution areas).ĭuring the import of those watershed elements, the user was required to define the mapping for A, B, and/or C parts for each element that was imported (review Watershed). When events are created using HEC-DSS files, HEC-FIA uses the watershed configuration that was associated with the inundation configuration to determine where the user has pre-defined output to be required. Therefore, it is recommended to store HEC-DSS and/or gridded hydraulic data in the shared directory within the HEC-FIA study directory to ensure that the file(s) are stored with the project and shared between individuals. Note: Defining hydraulic events in HEC-FIA allows the user to map or set the path to the file but this step does not copy the file. HEC-FIA accepts hydraulic data from HEC-DSS time-series and/or gridded files computed by a hydraulics model (e.g., HEC-HMS, HEC-RAS, HEC-ResSim, etc.). Once the inundation configuration is created, the hydraulic characteristics of an event must be defined.
