Model-Based Assessment of Coastal Aquifer Management Options. A GMDSI worked example report

Abstract

This GMDSI report describes a model that was built to explore options for management of a coastal aquifer in southern Portugal. The aquifer is representative of many around the world; if extraction continues at its present rate, it is only a matter of time before it suffers a serious degradation in quality. Extraction must therefore be reduced. Alternatively, or as well, recharge must be enhanced. Enough data has been gathered over the last 20 years to support estimation of aquifer properties and inflows. These estimates are enabled by history-matching; however they are cloaked in uncertainty.
