Research Scientist, Hydrogeology - Emeritus

Professional Interests

Ms. Chapman is interested in helping solve problems related to waste disposal, contaminant tranpsort, and water supply in arid regions where paleoclimates may continue to influence flow systems or pose uncertainties for the future. Previous and current work rely heavily on isotopic (stable and radiogenic) and geochemical tracers for evaluating recharge and paleohydrologic systems. Borehole logging, time-domain reflectometry, and analytic and numerical modeling are other techniques that have been useful in her work.
