* 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.
* When no [[GeoTiff]] is selected or imported, the clay thickness of [[Subsidence_area_(Subsidence_Overlay)|subsidence areas]] or [[Terrain_(Subsidence_Overlay)|Terrain properies]] are used to.

The clay thickness for the Subsidence Module at the start of the simulation can be specified 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.


Clay Thickness GeoTIFF specification
Description The thickness of the clay layer on the peat, for the calculation of the oxidation component of Subsidence.
Value Clay Thickness (m)


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)
