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 it is possible to 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.
