Oxidation formula (Subsidence Overlay)

The amount of subsidence due to oxidation is calculated by the following formula:

Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle S_O = d_{gw,y} \cdot a_{y} - d_{ct} \cdot b - c}

where

$S_{O}$ is the subsidence due to oxidation.

$d_{gw,y}$ is the calculated ground water depth for year y.

$a_{y}$ is the calculated a parameter value for the current year $y$.
