Terrain (Subsidence Overlay)
Revision as of 17:19, 9 February 2021 by Frank@tygron.nl (talk | contribs)
Terrains in a project have a number of properties which can influence the subsidence calculation. By default, because there is always both surface and underground terrain defined for the entirety of the project area, all cells can be given default values for these subsidence keys. The subsidence terrain keys can all be overridden by overlapping Subsidence Areas.
| Icon | Key | Unit | Range | Description | Default value |
|---|---|---|---|---|---|
 |
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 | |
 |
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 |
