Abstract

In this chapter, idealized groundwater flow systems containing two liquids, namely freshwater and saltwater, of different density separated by an abrupt interface are considered under steady-state conditions. Classical approaches to the determination of the shape of the interface at equilibrium related to the two benchmark problems, seawater intrusion in a costal aquifer, and saltwater upcoming beneath a partially penetrating pumping well, are reviewed. In particular, it is shown that Ghyben–Herzberg approximation for Dupuit–Forchheimer-based models provide practically valuable insight into the behavior of the groundwater systems under consideration.
