Groundwater level formula (Water Overlay)
Revision as of 14:32, 10 July 2020 by Frank@tygron.nl (talk | contribs)
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 WH_underground = \fract{W_sat}{WSP}}
Where:
- WLunderground = The groundwater level, relative to datum. Also known as the watertable.
- WHunderground = The height (column) of the saturated zone.
- Wsat = 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.
- Hsurface = The surface height in the cell, relative to datum.
- GBDM = The GROUND_BOTTOM_DISTANCE_M (effectively available height in the underground model).
- WSP = The WATER_STORAGE_PERCENTAGE of the underground terrain type.
