ABSTRACT
This chapter focuses primarily on solute transport in groundwater in aquifers. It starts with an introduction of the fundamental differences between the major types of aquifers, classified as confined and unconfined aquifers. Solute movement in these two types of aquifers differs due to different forces involved.
The similarities and the differences between solute transport in soils and aquifers, including the degree of saturation and the criteria for measuring the different properties, have been discussed in this chapter.
fPDEs in this chapter have been presented in different dimensions and coordinates (Cartesian and cylindrical), which are applicable to solute transport in mobile and immobile zones (based on fPDEs of distributed order in time and space) and to the relationship between flux and residential solute concentrations.
