User:Mburton/HydroGeoSphere Polygon Properties Dialog

The Polygon Properties dialog in the HydroGeoSphere model is where a polygon or polygons can be assigned a boundary condition. There are four options for the polygon properties, which are listed on the left side of the dialog: head, flux, rain, and potential evapotranspiration. The input parameters are shown on the right when one of the four boundary conditions is selected. Only one type of boundary condition can be assigned to a feature object on a boundary conditions coverage.

Polygon Properties dialog for the boundary conditions coverage

Head or Flux

Head and flux are two separate available arc property types on a boundary conditions coverage, but the input options available are the same. Head is a general specified head boundary condition, and flux is a general specified flux boundary condition. The input options for head and flux 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.
      • 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.
        • Interpolate
      • Time rasters – The Edit Table... button 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.
  • 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.
        • Interpolate – Causes time-varying values to be interpolated, resulting in a smoother application of the time-varying function.
      • Time rasters – 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.

Rain or Potential Evapotranspiration

Rain is a general specified flux boundary condition that converts fluxes to nodal volumetric fluxes. Potential evapotranspiration is a specified flux which is used in conjunction with evapotranspiration properties and is applied as a second-type boundary condition. Rain and potential evapotranspiration are two different polygon boundary condition options, but they contain the same input parameter options, which are listed below.

• Name – The name of the boundary condition. Names should be unique and contain no white space.
• 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.
    • Interpolate – Causes time-varying values to be interpolated, resulting in a smoother application of the time-varying function.
  • 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.
