Coastal areas are characterized by considerable demographic pressure that generally leads to groundwater overexploitation. In the Mediterranean region, this situation is exacerbated a recharge reduction enhanced climate change. The consequence water table drawdown alters freshwater/seawater interface facilitating seawater intrusion. However, salinity may also be affected other natural/anthropog...

Abstract:   A two-dimensional fully implicit finite difference model, which can be easily extended to three dimensions, is developed to study the effect of cut-off walls on saltwater intrusion into the aquifers. This model consists of a coupled system of two nonlinear partial differential equations which describe unsteady density-driven groundwater flow and solute transport. The numerica...

Abstract Time fluctuations of groundwater flux are known to affect solute transport and thus the width penetration seawater intrusion. Yet, most theoretical laboratory studies mixed‐convective processes accompanying intrusion assume constant extraction rates, even though real‐world pumping is usually intermittent. In this study, dynamic changes an experimental saltwater wedge caused by intermit...

Freshwater-seawater (FW-SW) temperature contrasts widely exist in natural coastal aquifers. The significant effects of thermal forcing on water flow and salinity distributions for homogeneous aquifers have been demonstrated recently, however, the impact heterogeneous remains unclear. This study conducted simulations variable-density flow, heat salt transport with Monte-Carlo realizations log-no...
