User:Mburton/HydroGeoSphere Point Properties Dialog

The Point Properties dialog in the HydroGeoSphere model is where the input parameters for nodes associated with the relative coverage are set. The boundary conditions, observations, and hydrograph coverages each have their own individual parameters under the Point Properties dialog, depending on which coverage is active. Only one type of boundary condition can be assigned to a feature object on a boundary conditions coverage. For hydrograph or observation coverages, "Hydrograph" or "Observation" is the only option available to assign to a feature object, relative to the coverage type.

Point Properties dialog for the boundary conditions coverage

Flux Nodal, Boundary Conditions Coverage

Flux nodal is a general specified flux boundary condition on the boundary conditions coverage of a HydroGeoSphere model. The input options for a flux nodal designation are listed below.

• Name – The name of the boundary condition. Names should be unique and contain no white space.
• Domain – The domain in which the boundary conditions are applied.
  • Porous media
    • Minimum sheet – The minimum node sheet; boundary conditions are applied between the minimum and maximum node sheets.
    • Maximum sheet – The maximum node sheet; boundary conditions are applied between the minimum and maximum node sheets.
    • Input type – How the boundary condition data is specified.
      • Time series – Time-varying values of the boundary condition. A table is generated using the XY Series Editor dialog that is opened by clicking the Edit XY Series button by either manually entering the data, or importing the data.
  • Surface flow
    • Input type – How the boundary condition data is specified.
      • Constant – Constant value of the boundary condition.
      • Time series – Time-varying values of the boundary condition. A table is generated using the XY Series Editor dialog that is opened by clicking the Edit XY Series button by either manually entering the data, or importing the data.
      • Time raster table – The Edit Table... opens the Time raster table dialog where the data is entered by selecting a raster from outside GMS.
    • Interpolate – Causes time-varying values to be interpolated, resulting in a smoother application of the time-varying function.
    • Nodal flux reduction by pressure head – Reduces flux as a function of the nodal pressure head to avoid pumping from the dry materials.

Point Properties dialog for the hydrograph coverage

Hydrograph, Hydrograph Coverage

The hydrograph option on the hydrograph coverage of a HydroGeoSphere model allows a point to be assigned a hydrograph during the model run. The only input available in the Point Properties dialog on a hydrograph coverage is a name. The name should be something descriptive, and less than 80 characters.

Point Properties dialog for the observation coverage

Observation, Observation Coverage

The observation coverage in a HydroGeoSphere model allows the creation of observation points. The input options for an observation point are listed below.

• Name – This should be a descriptive name for the observation point, and less than 40 characters.
• Interpolate – Output values are linearly interpolated from the nodal values at the vertices at the element that contains the observation point.
