Henk M. Haitjema

Hendrik Marten Haitjema (born 1947) is a Dutch and American engineer and hydrologist, and professor emeritus at Indiana University. He is recipient of the 2017 Keith A. Anderson Award of the National Ground Water Association. He is author of the book Analytic Element Modeling of Groundwater Flow and the widely used computational groundwater flow modeling system GFLOW.

Haitjema is originally from Dedemsvaart, The Netherlands.He earned an M.S. (Ingeniers) in Civil Engineering in 1976 from the Delft University of Technology.He came to America in 1978 and joined Professor Otto D.L. Strack at the University of Minnesota to work on the first computer model to implement the analytic element method for groundwater flow mechanics. He earned a Ph.D. in Civil Engineering in 1982 from the University of Minnesota and became an associate professor in the Department of Civil and Mineral Engineering at the University of Minnesota. In 1984, he joined the faculty of Indiana University as an Associate Professor to teach groundwater flow modeling and applied mathematics and was promoted to Full Professor in 1997. His research has been supported by the US Geological Survey, US Environmental Protection Agency, US Forest Service, US Department of Energy, National Institute for Global and Environmental Change, and the Indiana Department of Environmental Management. He retired from Indiana University in 2012.While at IU, he mentored 7 Ph.D. students, and numerous Masters students, several of whom produced a research thesis.He was Editor-in-Chief of the journal Groundwater from 2014 to 2020.
