Subsidence areas are conceptual areas which allow users to override subsidence related attributes of the underlying terrain.
| Icon | Key | Unit | Range | Description | Default value |
|---|---|---|---|---|---|
 |
SUBSIDENCE | boolean | Whether or not subsidence should be calculated for a terrain or in a given area. Subsidence is calculated when the value is not equal to 0. | false | |
 |
CLAY_THICKNESS | m | The thickness of the clay layer on the peat, for the calculation of the oxidation component of subsidence. | 0.2 | |
 |
PEAT_FRACTION | The fraction of the soil composed of peat, for the calculation of the compaction component of subsidence. | 0.4 | ||
 |
TOPLAYER_THICKNESS | m | The thickness of the layer covering the peat, for the calculation of the compaction component of subsidence. | 1.2 |
