Centrifuge Modeling of Unsaturated Flow

Participants: John McCartney, Eduardo Dell’Avanzi

Description: Centrifuge modeling of soil columns under 1g and Ng levels is being conducted to investigate the scaling factors of variables governing unsaturated flow through soil. This project seeks new methodologies for investigating the suction-saturation and suction-hydraulic conductivity curves. The overall objective is to contribute towards understanding of evapotranspirative cover systems.
