It is possible to include the effects of subsidence in the Water Overlay's calculations by using a Combo Overlay to precompute the resulting Elevation model, and setting the result as the terrain elevation prequel of the Water Overlay.

How to add subsidence to a water simulation:
  1. Add and configure a Subsidence Overlay (or other source which defines amounts of subsidence).
  2. Add a Heightmap Overlay, set to DTM mode.
  3. Add a Combo Overlay, which takes the values of the Heightmap Overlay and subtracts the value of the final result of the Subsidence Overlay.
  4. Open the Water Overlay's configuration wizard, and proceed to the step regarding the Elevation Model.
  5. Opt to select a Grid Overlay to determine the Terrain Elevation Model.
  6. Select the Combo Overlay.
  7. Recalculate the water Overlay.
  8. The calculation has now taken into account the specified subsidence effects.
