About the Authors

Leonard Konikow

Dr. Leonard Konikow is a Scientist Emeritus with the United States Geological Survey, where he was a research hydrologist for more than 40 years. He is also the Editor‑in‑Chief of Groundwater journal. His research interests include the development and application of simulation models for groundwater flow and contamination problems, groundwater-surface water interactions, coastal submarine groundwater discharge processes, and groundwater depletion. He is a member of the National Academy of Engineering, Fellow of the American Geophysical Union, and has received the M. King Hubbert Science Award and Life Member Award from the National Ground Water Association and the O.E. Meinzer Award from the Geological Society of America. He also received the President’s Award from the International Association of Hydrogeologists. He was the Birdsall Distinguished Lecturer for the Hydrogeology Division of GSA in 1986‑87. He served on several committees of the National Research Council and in leadership positions in several professional societies. He is author or coauthor of numerous scientific articles and reports.

John Bredehoeft

Dr. John Bredehoeft had a 32‑year career with the United States Geological Survey (USGS) as a research geologist and as a senior manager in their Water Resources Division. After retiring from the USGS, he went on to found a major geotechnical consulting firm. He had also served as Editor‑in‑Chief of Groundwater journal. He is a member of the National Academy of Engineering and recipient of several major awards and honors, including the Penrose Medal of the Geological Society of America, the Horton Award from AGU, the Meinzer Award from GSA, and the Life Member Award from the National Ground Water Association. He taught at the University of Illinois, Stanford, University of California ‑ Santa Cruz, and San Francisco State University. He served on numerous national advisory committees for the National Research Council, the National Science Foundation, and the Department of Energy. Bredehoeft is the author of more than 100 scientific papers in the refereed scientific literature. Together with George Pinder, they (1) developed and published the first widely used numerical groundwater flow model, and (2) the first widely used contaminant transport model.
