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)
These GeoTIFFs can be linked to the Subsidence Overlay using a GeoTIFF Overlay and configuring this as the prequel to the High ground water level.
Notes
- Specified as m below terrain height
- When no prequel is specified, the water levels of groundwater level areas are used to initialize groundwater levels.
