Dispersion Process and Saltwater Intrusion in Groundwater

  • Kuniaki Sato

Dispersion phenomena of solutes and pollutants (contaminants/tracers) in subsurface water and porous media have caught the interest of researchers since the 1960s. The mathematical formulation of problems in terms of hydraulics has been realized by applying mass conservation (including source or sink terms for dispersed matter), Fick’s law and empirical correlations on the parameters for linking practice and mathematical models.

Simultaneous two-phase-flow of seawater and freshwater in coastal aquifer with a sharp interface is one of the themes.

In this chapter, mathematical modeling for convective and hydraulic equations, their typical analytical solutions, and the methods to determine dispersion coefficients are discussed in addition to formulation of the saltwater-freshwater interface in coastal aquifers.
