==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)
==Notes==
* 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.

Name Prequel Underlying data Unit Range No data Description
Clay thickness CLAY_THICKNESS Subsidence Prequel m The thickness of the clay layer on the peat, for the calculation of the oxidation component of Subsidence.

The clay thickness for the Subsidence Module at the start of the simulation can be specified using a Grid Overlay.
In the Subsidence Overlay Wizard it is possible to import and add a GeoTIFF Overlay or to do nothing and proceed with the next step.
