Management of Island Aquifers by Simulation-Optimization - sland aquifers are coastal groundwater systems recharged solely by local  precipitation. These aquifers are typically lens-shaped and  particularly vulnerable to seawater intrusion (SWI), sea level rise, and  groundwater pumping. These effects may ultimately lead to increased  management costs and/or aquifer salinization. The management of island  aquifers, requires identifying pumping strategies that trade off the  groundwater supply cost, which depends mainly on pump operation and  water desalination treatment, against the intensity of SWI. In this  poster, we will present the results of a study in which these trade-offs  have been explored quantitatively using an optimization framework  combined with a variable density groundwater flow model. Our focus has  been on the San Salvador Island aquifer, Bahamas, for which we highlight  the precarious balance between the economics, the sustainability, and  the vulnerability of the groundwater system.
