Groundwater level formula (Water Overlay)

Groundwater level is calculated per cell.

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 h_s = \frac{V_s}{f_s}}

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 w_g = h_s + B_c - d_{b,c}}

Where:

$h_{s}$ = The height (column) of the saturated zone.

$V_{s}$ = The amount of water in the saturated zone. The height of the water column if the equivalent amount of water was placed on the surface.

$f_{s}$ = The WATER_STORAGE_PERCENTAGE of the underground terrain type, used here as a fraction.

Also known as the watertable.
