Well-withdrawal footprint map, Azraq Oasis, Jordan

Large groundwater withdrawals in the Azraq Oasis area, Jordan, have contributed to declining water levels in wells. This map shows the withdrawal footprint and observed water-level trends (labeled triangular symbols, from Goode et al. 2013). The footprint depth-rate index is 0.1 meter per year (m/yr), corresponding to a water-level decline rate of 1 m/yr, scaled by a
