High ground water prequel (Subsidence Overlay)

The initial high groundwater level in the Subsidence model can be initialized using a GeoTiff. In the Subsidence Overlay Wizard it is possible to select one of the Default data provided, to import a GeoTiff or to do nothing and proceed with the next step.

Template:GeoTiffSpec

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 a groundwater GeoTiff is not configured for the Water Overlay, the watertable is initialized using the WATER_LEVEL attribute of the water level area instead. For locations without water level areas, the water table is set to one meter below the surface.
