Richard W. HealyFor more than thirty years, Richard W. Healy has been conducting research for the US Geological Survey on groundwater recharge, water budgets of natural and human-impacted hydrologic systems, and fluid and contaminant transport through soils. He has aught numerous short courses on unsaturated zone flow and transport, and groundwater flow modelling. He first presented a short course on methods for estimating recharge in 1994, and over the intervening fifteen years the course has been presented to several hundred professionals and students. The material in that course has been expanded and refined over the years and forms the basis of Estimating Groundwater Recharge. Healy has authored more than sixty scientific publications and is developer of the VS2DI suite of models for simulating water, solute, and heat transport through variably saturated porous media. He is a member of the Soil Science Society of America, the American Geophysical Union, and the Geological Society of America. Read More Read Less
