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 |
Notes
- Clay thickness defined in a Subsidence area is ignored when a clay thickness geotiff is used.
