Characterizing Mass and Energy Transport at Different Scales Grant uri icon



  • Agricultural soils containing appreciable amounts of active clay minerals exhibit shrink-swell behavior in response to changes in soil water content and chemical composition of the soil solution. This causes a number of management and environmental problems such as impaired infiltration, surface sealing, soil erosion, and preferential flow and transport. This research addresses the unresolved problem of linking fundamental theory on clay shrink-swell behavior with pore-scale geometrical, hydrostatic, and hydrodynamic considerations towards development of predictive models for hydraulic functions of swelling soils.
