Feature points and nodes in GSSHA have several attributes that can be modified. The Properties dialog allows modification of the various attributes of feature arcs.

WMS automatically assigns the correct type (generic, link break, or junction) to each point/node based on the type of feature arcs connected to the node, although the point/node type is not displayed in the dialog. This dialog for feature points and nodes in GSSHA lists the various attributes associated with each feature point or note.

This dialog is accessed either by double-clicking on a feature point or node or by selecting the Feature Objects | Attributes... menu command while in the Map module. Most of the attributes can be changed in this dialog, or by clicking a button in this dialog to open a separate dialog. The options for feature arcs are described in the GSSHA Feature Arcs article.

Properties Dialog

The Coverage Properties dialog is where the attributes are associated with feature points and nodes.
The Properties dialog is where the attributes are associated with feature points and nodes. Scroll to the right to see the full dialog.
ID
A unique ID assigned automatically by WMS. Not user editable.
Link
The link number, assigned by WMS to nodes that have hydraulic structures defined. Not user editable.
Hydraulic structures
Clicking Dot dot dot button.png brings up the GSSHA Hydraulic Structures dialog.
Hydrograph output
Turning on this option outputs a hydrograph for the outlet cell location to the OTL file. GSSHA can output hydrographs at specific nodes to the *.ohl file.
Sediment output
If the Soil Erosion option is selected in the GSSHA Job Control dialog, this option can be used to tell GSSHA to output the sediment load versus time at this location to the OSL file.
Groundwater BC
A drop-down of groundwater boundary conditions for modeling groundwater interaction. See GSSHA Groundwater for more information.
  • "Generic" – No special boundary is desired. The default option.
  • "Constant Head" – Groundwater level in the cell remains constant during the simulation. Value taken from the initial values assigned.
  • "Static Well" – The cell will have a source/sink term of constant rate. Makes the Pump rate (m3/s)" column appear.
  • "Dynamic Well" – Indicates that a dynamic, temporally varying, pumping well exists in the cell. Makes the Pump rate" column appear.
Pump rate (m3/s)
Enter a decimal daily pump rate in m3/s.
Pump rate
Click Pump Rate to bring up the XY Series Editor dialog. This allows a time varying pump rate to be entered.
