The initial high groundwater level in the Subsidence Module at the start of the simulation can be initialized using a prequel Grid Overlay. In the Subsidence Overlay Wizard it is possible to select one of the Default datasets provided, to import and create a GeoTIFF Overlay or to do nothing and proceed with the next step.

Default data

For the Netherlands, a number of groundwater GeoTIFFs are provided by default, based on data provided by The Netherlands Hydrological Instrumentarium:

  • NL_GHG_kk-nhi (Average highest watertable)
  • NL_GLG_kk-nhi (Average lowest watertable)
  • NL_GVG_kk-nhi (Average spring watertable)

These GeoTIFFs can be linked to the Subsidence Overlay using a GeoTIFF Overlay and referencing it with this prequel.

Notes

  • Specified as m below terrain height
  • When no prequel is specified, the water levels of groundwater level areas are used to initialize groundwater levels.
