GSSHA in the data tree.

Multiple GSSHA models using the same 2D grid can be managed within a single instance of WMS. The models are displayed in the data tree, where the user can edit the job control, precipitation, GSSHA coverage, index maps, and continuous maps.

Job Control – The job control for the active GSSHA model can be accessed from the GSSHA menu item. The job control can also be opened by right-clicking on the job control icon that corresponds with the desired GSSHA model and selecting Edit.

Precipitation – The precipitation for the active GSSHA model can be accessed from the GSSHA menu item. The precipitation can also be opened by right-clicking on the precipitation icon that corresponds with the desired GSSHA model and selecting Edit.

GSSHA Coverage – When a GSSHA model is created, it is a assigned a GSSHA coverage (if a GSSHA coverage does not already exist, WMS creates one). To change the assigned GSSHA coverage, right-click on the coverage icon that corresponds with the desired GSSHA model and select the GSSHA coverage that is to be assigned.

Index Maps – All index maps for all GSSHA models are shown in the data tree under the grid. To assign a map to a specific GSSHA model, right-click on the Index Maps folder under the desired GSSHA model, select Assign, and then select the index map that is to be assigned. To unassign an index map, right-click on the map and select Remove.

Continuous Maps – All continuous maps for all GSSHA models are shown in the data tree under the grid. To assign the maps to a specific GSSHA model, right-click on the Continuous Maps folder under the desired GSSHA model, select Assign, and then select the index map that is to be assigned. To unassign a continuous map, right-click on the map and select Remove.

Solution – Once a GSSHA model has successfully run, the solution is shown underneath the model in the data tree. If the solution already exists, it can be read in by right-clicking on the model's project name and selecting Read Solution.

Most of the options available under the GSSHA menu are also found in the right-click menu of the GSSHA project in the data tree. When selected from the GSSHA menu, they are performed on the active model. When selected from the right-click menu, they are performed on the corresponding model.

GSSHA Groups

Saving GSSHA Groups – Multiple GSSHA scenarios can be saved together as a group. To do this, right-click on the 2D Grid Folder and select Save GSSHA Group. A dialog will appear prompting to select which scenarios to save. Also pick a location for WMS to save the scenarios and the GSSHA Group File (*.ggp).

Opening a GSSHA Group – To open a group of GSSHA scenarios, right-click on the 2D Grid Folder and select Open GSSHA Group and select the GSSHA Group File (*.ggp) that are to be opened. This will open each project that corresponds with this group. There is also the option to open the solutions, if they exist.

Running a GSSHA Group – To run multiple GSSHA scenarios, right-click on the 2D Grid Folder and select Run GSSHA Group. A dialog will appear to select which projects to run. These projects will be saved as a group and then WMS will run each GSSHA scenario in the group.
