Chemical and Mass Transport

Current projects in this research area of the Fundamental & Exploratory Research Program of the Earth Sciences Division at LBNL are focused on nanoparticle and colloid transport in unsaturated porous media and rock fractures, chemical transport in structure porous media, unsaturated fast flow in fractured rock, and production and evaluation of coupled processes for CO2 in aquifers. The nanoparticle research focuses on the mobile fractions and natural abundance in soils. Also studied is the rate of infiltration in the unsaturated zone, an important issue in studying and defining the driving forces and boundary conditions in the containment and cleanup of contaminants in the subsurface.
