Saline water Intrusion in Heterogeneous Coastal Aquifers
Seawater intrusion (SI) into coastal aquifer is one of the main challenges for water resources management. SI is an environmental phenomenon naturally balanced by the groundwater flowing toward the ocean. However, excessive pumping, climate changes or sea level variations can induce severe declines in coastal groundwater levels, favouring the landward intrusion of saline water. A little amount of seawater (around 1%) is enough to contaminate a whole freshwater system and render its water unfit for drinking. Populations living along the coast are dependent mainly on freshwater extracted from coastal aquifers. Since a large portion of the world’s population is dwelling in coastal zones, SI has become a global issue that has promoted a worldwide research effort.
In the past few years, numerous studies have been conducted to understand saltwater intrusion processes. Laboratory-scale aquifers have been widely used as a tool to characterise freshwater-saltwater interfaces, and investigate the behaviour of saltwater wedges. However, most of these experiments were for homogeneous settings; which is not representative of the geological conditions present in real aquifers. Further investigation is still needed to comprehend the comportment of salt wedges in typical heterogeneous geological formations. This would help to provide more accurate SI predictions and better understand real-world coastal aquifer dynamics. Using an experimental approach, we will study saltwater intrusion in common heterogeneous configurations. Numerical models will then be used to simulate the experimental results and assess their consistency.
