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.
Note that when generating hydrographs, WMS will display the hydrograph solution for multiple scenarios in the same hydrograph.


==GSSHA Simulations==
[[File:WMS Project Explorer with two GSSHA simulations.png|thumb|right|200 px|WMS Project Explorer showing two GSSHA simulations.]]
There are several different types of entries within a GSSHA simulation. Many of the options available under the [[WMS:GSSHA Menu#2D Grid Module GSSHA Menu|''GSSHA'' menu]] are also found in the right-click menu of the GSSHA project in the Project Explorer.


[[Image:GSSHAMultipleModels.png]]
Note that:
*Selecting an item from the ''GSSHA'' menu performs the desired option on the active simulation.
*Selecting an item from the right-click menu performs the desired option on the corresponding simulation (this can be done even if the simulation is not active).  


Below are common functions available through either of those methods.


'''Job Control''' – The [[WMS:GSSHA Job Control|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'''.
===Job Control===
Selecting '''Job Control...''' from the ''GSSHA'' menu brings up the [[WMS:GSSHA Job Control|''Job Control Parameters'' dialog]] for the active GSSHA simulation. This dialog can also be accessed by right-clicking on the "[[File:GSSHA Parameters Icon.svg|14px]] Job Control" entry under a specific GSSHA simulation and selecting '''Edit...'''.


'''Precipitation''' – The [[WMS:GSSHA Precipitation|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'''.
===Precipitation===
Selecting '''Precipitation...''' from the ''GSSHA'' menu brings up the [[WMS:GSSHA Precipitation|''GSSHA Precipitation'' dialog]] for the active GSSHA simulation. This dialog can also be accessed by right-clicking on the "[[File:GSSHA Parameters Icon.svg|14px]] Precipitation" entry under a specific GSSHA simulation 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 you want to assign.
===GSSHA Coverage===
When a GSSHA simulation is created, it is a assigned a GSSHA coverage (if a GSSHA coverage does not already exist, WMS creates one).  To change the GSSHA coverage assigned to a specific simulation, right-click on "[[File:Coverage Active Icon.svg|14px]] GSSHA" underneath the desired GSSHA simulation and select ''Assign Coverage'' | '''[CoverageName]''' (where "[CoverageName]" is the name of the desired GSSHA coverage). Note that only coverages of the type "GSSHA" will be listed. The name of the coverage can be changed as desired as long as the type remains "GSSHA".


'''Index Maps''' – All [[WMS:GSSHA Maps|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 you want to assign.  To unassign an index map, right-click on the map and select '''Remove'''.
===Index Maps===
All existing [[WMS:GSSHA Maps#Grid Index Maps|grid index]] and [[WMS:GSSHA Maps#Stream Index Maps|stream index maps]] are listed under the "[[File:Generic Folder.svg|14px]] Index Maps" folder under the 2D grid in the Project Explorer. Index maps assigned to a specific GSSHA simulation are listed under the "[[File:GSSHA Folder.svg|14px]] Index Maps" folder under each GSSHA simulation.  


'''Continuous Maps''' – All [[WMS:GSSHA Maps|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 you want to assign.  To unassign a continuous map, right-click on the map and select '''Remove'''.

Multiple GSSHA simulations using the same 2D grid can be managed within a single instance of WMS. The simulations are displayed in the Project Explorer, where it is possible to edit the job control, precipitation, GSSHA coverage, index maps, and continuous maps.

Note that when generating hydrographs, WMS will display the hydrograph solution for multiple scenarios in the same hydrograph.

GSSHA Simulations

WMS Project Explorer showing two GSSHA simulations.

There are several different types of entries within a GSSHA simulation. Many of the options available under the GSSHA menu are also found in the right-click menu of the GSSHA project in the Project Explorer.

Note that:

  • Selecting an item from the GSSHA menu performs the desired option on the active simulation.
  • Selecting an item from the right-click menu performs the desired option on the corresponding simulation (this can be done even if the simulation is not active).

Below are common functions available through either of those methods.

Job Control

Selecting Job Control... from the GSSHA menu brings up the Job Control Parameters dialog for the active GSSHA simulation. This dialog can also be accessed by right-clicking on the "GSSHA Parameters Icon.svg Job Control" entry under a specific GSSHA simulation and selecting Edit....

Precipitation

Selecting Precipitation... from the GSSHA menu brings up the GSSHA Precipitation dialog for the active GSSHA simulation. This dialog can also be accessed by right-clicking on the "GSSHA Parameters Icon.svg Precipitation" entry under a specific GSSHA simulation and selecting Edit....

GSSHA Coverage

When a GSSHA simulation is created, it is a assigned a GSSHA coverage (if a GSSHA coverage does not already exist, WMS creates one). To change the GSSHA coverage assigned to a specific simulation, right-click on "Coverage Active Icon.svg GSSHA" underneath the desired GSSHA simulation and select Assign Coverage | [CoverageName] (where "[CoverageName]" is the name of the desired GSSHA coverage). Note that only coverages of the type "GSSHA" will be listed. The name of the coverage can be changed as desired as long as the type remains "GSSHA".

Index Maps

All existing grid index and stream index maps are listed under the "Generic Folder.svg Index Maps" folder under the 2D grid in the Project Explorer. Index maps assigned to a specific GSSHA simulation are listed under the "GSSHA Folder.svg Index Maps" folder under each GSSHA simulation.

Right-clicking on "Generic Folder.svg Index Maps" gives the following options:

To assign a map to a specific GSSHA simulation, right-click on the "GSSHA Folder.svg Index Maps" folder under the desired GSSHA simulation and select Assign | [DesiredIndexMap], where "[DesiredIndexMap]" is the name of the index map to be assigned. To immediately remove (or unassign) an index map from a specific GSSHA simulation, right-click on the index map and select Remove.

Right-clicking an index map under the "Generic Folder.svg Index Maps" folder gives several options:

  • Rename – Allows the index map to be renamed.
  • Export Dataset... – Opens a File Formats dialog.
  • Export to KMZ... – Opens a Save dialog where a File name and save location can be specified for saving the GSSHA index map file as a Google Earth Vector (KMZ) file.
  • Delete – Immediately deletes the selected index map.
  • Properties... – Opens the Dataset Info dialog.
  • View Values... – Opens the Edit Dataset Values dialog.
  • Contour Options... – Opens the Contour Options dialog for the selected dataset.
