Groundwater contamination is a great risk to the environment. Designing modern landfills is a solution made to contain the contaminants and prevent further leakage through the soil. Hydraulic conductivity of soils affects many geoenvironmental processes as well as design parameters, and is mostly dependent on fluid viscosity, grain-size distribution, and void ratio of the porous medium. Due to dipole properties of water molecules in a porous medium, any electric field will align molecules to the direction of the field. An alternating electric field oscillates individual water molecules and incites a change in water flow patterns through the porous medium. In this study the effect of electromagnetic waves (EM) on the hydraulic conductivity of soils is investigated.
