WMS:GSSHA Menu

The GSSHA model has two menus: one that can be accessed through Map module and the other through the 2D Grid module.

Map Module GSSHA Menu

This menu is available when a GSSHA coverage is the active coverage, or if WMS is switched to the Map module.

Smooth Stream/Pipe Arcs...

Opens the Smooth GSSHA Streams dialog.

Read Stream Elevation...

Brings up the Open dialog. Select the desired elevations file to import, then click Open.

Update Lake Cells

 

Renumber Links

Automatically reorders and numbers links and nodes in a stream channel. See the GSSHA Channel Routing article for more details.

Renumber Storm Drains

Automatically reorders and numbers links and nodes in a storm drain arc.

2D Grid Module GSSHA Menu

This menu is available when the 2D Grid module is active.

Open Project File...

Brings up the Open dialog. Browse to and select the desired GSSHA project file to open, then click Open. A GSSHA project file begins with the first content line either being "GSSHAPROJECT" or "CASC2DPROJECT". Once a valid project file has been identified, WMS will import all of the files needed for input to GSSHA.

Note that the channel input file is not imported. Instead, the channel input information is re-created from the WMS map file that stores the GSSHA coverage.

To import a GSSHA output file, use the Read Solution command.

Open Group...

Brings up the Open dialog. Browse to and select the desired GSSHA group file to open, then click Open. See the GSSHA Multiple Scenarios for more details.

Save Project File...

Opens a Save GSSHA Project File dialog. Browse to the desired save location, enter the desired File name, and click Save to save the GSSHA project file and all associated GSSHA input files. WMS automatically uses the GSSHA project file name as a prefix for all GSSHA input files. The only exception is for index map files, which are assigned default names using the convention "id_map_##.idx", where "##" is automatically generated by WMS. All files are saved to the same directory. For long term simulations, WMS copies the HMET file from its original location to the new GSSHA project directory.

For more detailed management of the GSSHA input and output files names, see the Save GSSHA Project File dialog.

Save Group

Opens the Save GSSHA Group File dialog for saving a GSSHA group file.

Job Control

Opens the GSSHA Job Control Parameters dialog. The GSSHA Job Control Parameters dialog contains options and data for computational processes in a GSSHA simulation are specified. See GSSHA Job Control for more information.

Clean Digital Dams

Runs the CleanDam algorithm. Digital dams occur where a stream leaves a cell at or near a corner. See GSSHA Digital Dams for more information.

Precipitation

Opens the GSSHA Precipitation dialog.

Maps

Opens the GSSHA Maps dialog.

Map Tables

Brings up the GSSHA Map Table Editor.

Renumber Links

Automatically reorders and numbers links and nodes in a stream channel.

Renumber Storm Drains

Automatically reorders and numbers links and nodes in a storm drain arc.

Model Check

GSSHA Model Check dialog

Runs through the input data for a GSSHA simulation and looks for obvious inconsistencies and problems with the model. The model checker will not identify values that are outside of plausible ranges, etc., only logical problems. For example, an index map has one or more cells whose ID is 0 (which is not allowed in GSSHA), or a specified process that has an ID with parameters whose values are 0.00 (which indicates an incomplete entry). An example of a problem that the model checker would not find is if a stream arc has a pit that pools water.

Run GSSHA

Launches the GSSHA model run. Select an existing GSSHA project file or specify the name and location of the GSSHA project file to be saved before running the simulation. The GSSHA Run Options include:

• Suppress screen printing
• Save files before running
• Pause GSSHA window after running

The Suppress screen printing option suppresses the output of runtime data from GSSHA at each time step, but significantly reduces the overall run time required for a GSSHA simulation. This option also requires that the GSSHA input files be saved before running the simulation.

GSSHA Run Options dialog

WMS will automatically read the GSSHA solution produced by the simulation when the Close button is clicked in the WMS Model Wrapper if the Read Solution on Exit option is toggled on.

Note: GSSHA currently supports file names (including path and file name) with lengths less than or equal to 128 characters. If GSSHA tutorial files are placed in a directory with a path that causes the combined path and file name to exceed 128 characters, then GSSHA will not run.

Run GSSHA Group

Opens the Save and Run GSSHA Group dialog to select which projects to run.

Read Calibration Output

 

Read Solution

Brings up a browser to open a GSSHA solution file and all of the associated datasets. After import, WMS lumps the solution file and all associated datasets together into a solution folder in the Project Explorer. All of the datasets in the folder are treated as regular datasets. Organizing the datasets into a solution allows several solutions to be in memory at the same time. Several dialogs look for solutions and the associated datasets to set up and display output graphs. Along with the regular datasets, the summary file for the project is also accessible for each solution by double-clicking the summary file project explorer item under the solution folder.

Individual solution output time series data for a cell may be viewed from the Solution Results dialog accessed from the Feature Point/Node Type dialog. This dialog will only show the output dataset time series for the cell that underlies the feature point selected. To compare the solution output at a cell with observed data, see the GSSHA Observation Points section.
