摘要

Coastal aquifers involve varying conditions in time and space, owing to the occurrence of free and moving boundaries, leading to upconing due to intensive pumping near the coast. A numerical procedure is developed for solving the location of these interfaces in steady and transient conditions with the Galerkin finite element technique. The conceptual approach developed to solve the finite element matrix equations is presented. Benchmark tests which involve confined and phreatic groundwater flow in coastal aquifers, are studied to demonstrate the capability of the present approach of predicting accurate results, including aquifers involving saltwater interface upconing. The model was also applied to the coastal aquifer of Martil in Morocco to simulate groundwater flow and to study effects of the seawater intusion interface under the ONEP (Office National de l'Eau Potable) pumping well rates.
