Mean annual groundwater recharge depth in transboundary aquifers

Mean annual groundwater recharge depth is calculating by dividing the long-term mean groundwater recharge, including man-made components (returnflows, induced recharge, artificial recharge), by surface area of the whole aquifer. Indicator is expressed as mm/yr. For more information, visit the Transboundary Water Assessment Programme Portal on groundwater: https://ggis.un-igrac.org/ggis-viewer/viewer/twap/public/default
