The clay thickness for the Subsidence Module at the start of the simulation can be specified 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.
| Clay Thickness GeoTIFF specification | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Description | The thickness of the clay layer on the peat, for the calculation of the oxidation component of Subsidence. | ||||||||
| Value | Clay Thickness (m) | ||||||||
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.
