WMS:GSSHA Solution Analysis

GSSHA Solution Analysis dialog.

The GSSHA Solution Analysis dialog is primarily used for manual calibration as well as visualizing solution results. It is accessed by clicking the button in the Solution Results column in the GSSHA feature points/nodes Properties dialog.

There are two types of solution analysis:

• Datasets
• Summary file

Options specified in the spreadsheet in the upper portion of the dialog control what is shown in the tabs below. The Filters row in the spreadsheet is used to filter the results shown in the spreadsheet based on Name, Type, or Event. Use the toggle in the Display column to toggle on the display of all datasets shown in the spreadsheet.

Datasets

Both observations and gridded and link/node datasets that are part of all GSSHA solutions are shown in the spreadsheet. Anything shown in the spreadsheet with the Display toggled on is used for generating the Compare and Residuals plots and for computing Statistics using the residuals.

Summary file

After running the GSSHA simulation, GSSHA writes a summary file. The results for each event of the simulations is stored in WMS and shown in the spreadsheet. The observations are also listed in the spreadsheet, which if toggled on will be plotted with the solution results. This tool can be especially useful when running GSSHA in batch mode. View a plot of the simulations in order to determine which of the runs produce results similar to the observed data.
