    Highly gravity-driven flow of a NAPL in water-saturated porous media using the discontinuous Galerkin finite-element method with a generalised Godunov scheme

    In this paper, we develop an implementation of gravity effects within a Global Pressure formulation in a numerical scheme based on the implicit pressure explicit saturation (IMPES) approach. We use the Discont...

    Large Scale Experiment on Transport of Trichloroethylene in a Controlled Aquifer

    Pollution by dense non-aqueous phase liquids (DNAPLs) represents a major threat to groundwater resources. In a real case of site contamination, the efficiency of remediation techniques is often limited by a la...

    Surfactant Enhanced In Situ Remediation of LNAPL Contaminated Aquifers: Large Scale Studies on a Controlled Experimental Site

    A central problem in a real case remediation of an oil contaminated site is the knowledge of the volume and the extent of the pollution. As the estimation of the mass balance, usually based on some point measu...
