The initial low 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.


Low Groundwater GeoTIFF specification
Description The depth of the ground water level, relative to the surface.
Value Low Groundwater level (m below terrain height)

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)
