Research Description

Anderson's primary research interests include evaluation of soil management effects on soil hydraulic properties, development of X-ray computed tomography and microtomography techniques for assessment of pore-scale soil properties and processes, and utilizing simulation models to evaluate effectiveness of conservation practices at the watershed scale. Soil properties evaluated with X-ray tomography include macropore and mesopore size distributions and characteristics, pore continuity, and pore tortuosity--all critically important for transport of water, air and solutes in soil systems. Fractal and fuzzy logic techniques are applied to quantify pore-scale variability of biopores.
