Abstract(s)

Analytical and numerical models were applied to an oceanic peninsula to estimate the volume of freshwater available, and the amount of water that could be pumped without depleting the resource. The analytical models were used at regional scale, whereas the numerical models were applied in a small domain to obtain the hydrogeologic parameters of the aquifer. The results showed that even small pumping rates of 10% of the annual net recharge would have important impacts in the thickness of the water lens, which can be even higher during dry years, when the annual recharge may be half of the multiple-year long-term average value.
