Subsidence (Water Overlay)

This functionality is deprecated and will be removed in the future.
Subsidence is a process by which the terrain slowly lowers over time. If a Subsidence Overlay is available, the Water Module's simulation can take the effects of subsidence into account.
When a Subsidence Overlay is linked to the Water Overlay, the effects of subsidence (as calculated in its final timeframe) are applied to the Elevation model. The result of that application is used for the entirety of the Water Overlay's calculations. In other words, the calculations are run in sequence, not in parallel.
Notes
- Subsidence is an optional connection. If no Subsidence Overlay is connected to the Water Overlay, no subsidence is assumed to be applied to the Elevation model.
- The effect does not work the other way around. Results from the Water Module are not used directly as input for the subsidence overlay. However, users can export ground watertable results from a water overlay to use as static input for a subsidence overlay.
