GSSHA Map Tables

The following options are available on this tab:

  • Using index map – A drop-down listing all available index maps in the project. Select the desired index map from the list.
  • Index map type – A drop-down list of index map types in the project. Select the desired type.
  • Generate IDs – Generates a list of IDs from those found in the selected index map.
  • Add ID – Adds a new ID to the spreadsheet, allowing manual creation of a new ID.
  • Delete ID – Immediately deletes the selected ID.

The spreadsheet displays all of the IDs in the selected index map, one per column. It has the following rows:

  • ID – A unique type ID.
  • Description1 – An alphanumeric field. Enter a concise descriptive name for the ID type.
  • Description2 – An optional alphanumeric field. Enter additional concise descriptive information.
  • Initial temperature plot
  • Computational node depths
  • Thickness of soil layer (m)
  • Phase change temperature (C)
  • Volumetric soil water content – Fraction of 1
  • Volume of unfrozen water – Fraction of 1
  • Unfrozen water parameter "A"
  • Unfrozen water parameter "B"
  • Unfrozen water parameter "C"
  • Thawed soil thermal conductivity – W m−1 k−1
  • Frozen soil thermal conductivity – W m−1 k−1
  • Volumetric heat capacity – J m−1m−1m−1k−1
