Characterization of Flow and Transport Processes in Soils at Different Scales Grant uri icon

Overview

abstract

  • Some of the most productive agricultural soils contain appreciable amounts of active clay minerals and exhibit shrink-swell behavior in response to changes in soil water content and chemical composition of the soil solution, leading to surface sealing, impaired infiltration, erosion, and preferential flow. 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.
