Dr. Ron Green’s appreciation for hydrology dates to his time as a Peace Corps volunteer in Cameroon Africa in the early 1970s where he worked on a rural water-resource project. After completing his studies in Hydrology at the University of Arizona and a brief stint in environmental consulting, he spent his career at Southwest Research Institute working in applied research. In the early years of his career he focused on safe disposal of highly radioactive waste (HLW) in fractured rock. During subsequent years he worked on assessment of water resources targeting karst terrains in arid and semi-arid environments. He served as chair of the National Cave and Karst Research Institute Board. He recently co-edited a memoir titled “The Edwards Aquifer: The Past, Present, and Future of a Vital Water Resource” in which he authored several chapters. He is a Fellow of the Geological Society of America in recognition of his work in flow and transport in karst media.
