Environmental Geotechnics deals with a wide variety of applications, such as the characterization of polluted sites and landfill waste, the design of containment systems for subsoil pollutant control, radioactive waste disposal, geo-energy exploitation and bacteria-driven soil modification, among others. Reliable and effective predictions of the actual behaviour and performance of these very complex systems require a deep understanding of the coupled hydro-bio-chemo-mechanical phenomena that occur at very different scales. Future progress in the scientific state of the art and substantial...
