Abstract:
Two regional aquifers are analyzed based on their stable isotope and hydrochemical data. The Tucson basin (Arizona) and Madrid basin (Spain), present similarities in their geologic patterns. The ground-water flow regimens, however, are different. Madrid basin presents local, intermediate and regional flow. Rivers in the Madrid basin are perennial, while Tucson washes only drain surface run-off. The winter precipitation is the main source for recharge in both basins. This was deduced by the difference in oxygen-18 content between winter and summer precipitation over both basins. Madrid basin presents a continental effect occurring from west to east and an altitude effect from northeast to southwest. Tucson basin presents an altitude effect. The oxygen-18 content decreases toward the higher elevations. Mixing of waters in discharge areas in both basins due to anthropogenic activity masked relationships, if any, among the stable isotopes and hydrochemical species.
