The amount of subsidence due to oxidation is calculated by the following formula:
where
- is the subsidence due to oxidation.
- is the calculated ground water depth for year y.
- is the calculated a parameter value for the current year .
- is the clay thickness of the terrain, defined by CLAY_THICKNESS
- is the b parameter value, defined by PARAMETER B
- is the c parameter value, defined by PARAMETER C
This formula was provided by experts, who have derived this formula empirically.
