Over the last 10 years, Prof. Weisbrod has focused his research on contaminant hydrology in general, and processes at the Earth-atmosphere, fracture flow and colloidal transport in particular. Since his return to Israel, he has focused on studies related to the mechanisms controlling colloid-facilitated transport in the subsurface, under a variety of environmental conditions. Another research direction is related to the processes occurring within fractures in the upper vadose zone under arid conditions and their relation to groundwater salinization and Eath-atmosphere gas exchange. A large portion of his current research focuses on unsaturated-zone conditions, where processes at the air-fluid-solid interface play an important role. Processes occurring at the interface between fluids, phases and the fluid-matrix, as well as the transition between scales, are of special interest. Understanding transport phenomena in the subsurface usually requires micro-scale experimental work. Nevertheless, Prof. Weisbrod is trying to tie his research to larger scale and field-scale processes
