The subsidence overlay also has [[attribute]]s. All attributes have a default value, but can be changed to configure the subsidence calculation.
The [[Subsidence (Overlay)|subsidence overlay]] also has [[attribute]]s.

| When passive drainage is applied, the GHG (highest ground water level) is increased by this amount.

| Due to definitions "Increase" means that the distance between the surface and this ground water level increases. The default value causes the ground water level to come closer to the surface.

| [[LOW_PASSIVE_DRAINAGE]]
| When passive drainage is applied, the GLG (lowest ground water level) is increased by this amount.
| 0
| Due to definitions "Increase" means that the distance between the surface and this ground water level increases. The default value does not affect the ground water level.
|-
| [[Years (Subsidence Overlay)|YEARS]]
| The amount of years to simulate during the calculation, in 1-year steps. It's possible to set this value anywhere between 1 to 1000.
| 30
| This attribute is linked to one of the keys of the overlay. When this attribute is changed the key is changed as well.
