High ground water prequel (Subsidence Overlay)
Revision as of 12:20, 17 January 2022 by Frank@tygron.nl (talk | contribs)
The initial high 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.
| High Groundwater GeoTIFF specification | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Description | The depth of the ground water level, relative to the surface. | ||||||||
| Value | High 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)
Notes
- When no GeoTIFF is selected or imported, the water levels of groundwater level areas are used to initialize groundwater levels.
