* When no [[GeoTiff]] is selected or imported, the water levels of [[Ground_water_level_area_(Subsidence_Overlay)|groundwater level areas]] are used to initialize groundwater levels.

The initial high groundwater level in the Subsidence Module at the start of the simulation can be initialized using a GeoTiff.
In the Subsidence Overlay Wizard it is possible to select one of the Default datasets provided, to import a GeoTiff 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)
