Groundwater in the Tygron Platform is modeled in the form of a GeoTiff.
Groundwater is only used when the GROUND WATER attribute of the Water Overlay is set to complete, meaning the underground model is fully active.
Values in the groundwater GeoTIFF respersent the initial distance between the surface and the watertable. A greater value in the GeoTiff will result in a lower watertable. 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 height (relative to the datum).
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)
