Oxidation formula (Subsidence Overlay): Difference between revisions

Revision as of 10:53, 16 February 2021

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

$S_{O}=d_{gw,y}\cdot a_{y}-d_{ct}\cdot b-c$

where

S_{O}

is the subsidence due to oxidation.

d_{gw,y,c}

is the calculated ground water depth for year y in cell c.

a_{y}

is the calculated a parameter value for the current year

y

.

d_{ct,c}

is the clay thickness of the terrain in cell c, defined by CLAY_THICKNESS

b

is the b parameter value, defined by the model attribute B

c

is the c parameter value, defined by the model attribute C

This formula was provided by experts, who have derived this formula empirically.
