Which outcome during sea level rise increases saltwater intrusion into fjordic groundwater aquifers?

💡 Explanation

As sea level rises, saltwater intrudes further inland because the saline interface migrates upwards due to density differences between saltwater and freshwater following Ghyben–Herzberg relation. Therefore, upward migration of the saline interface leads to increased salinity within groundwater aquifers, rather than increased runoff, hydraulic gradient decrease or evaporation decrease having direct impacts.
