What is the Subsidence Overlay
The Subsidence Overlay is an overlay that shows which places in the 3D world are subject to subsidence due to oxidation and/or compaction of peat. The calculations can give result about the subsidence, and the effects it has on ground water levels. To add a subsidence overlay go to Geo Data -> Overlays -> Add Subsidence.
The Subsidence Overlay can be used to calculate the amount of subsidence which takes place on peat soil, specifically due to peat oxidation and compaction. The calculations are specific for peat soil. Separate formulas for other soil types have not yet been implemented. Although it's possible to use the overlay to give an impression of subsidence resulting from other factors, the results will be less accurate. This means that results have a greater margin of error for different use-cases.
It is possible to add multiple subsidence overlays to a project. By varying their configuration slightly, it is possible to calculate multiple scenario's or time-frames simultaneously.
