Scenario-Based Modelling of Contaminant Transport in the Karst Vadose Zone of Avetrana (Southern Italy): An Applied Case Study Using the Equivalent Porous Medium Approach
Groundwater is among the most vital freshwater reserves worldwide, accounting for roughly 25–40% of global drinking-water supply. Where karst aquifers occur, dissolution-enhanced fracture networks make these systems especially prone to contamination. This study presents a scenario-based three-dimensional numerical case...
