Mahdi Salih Hantush, Professor of Hydrology at the University of Kuwait, died on January 14, 1984 from complications following heart surgery.
A hydrologist, scientist, and great teacher, Mantush specialized in the application of mathematics to the solution of transient groundwater flow problems. His particular expertise in the development of well-flow equations led the late R.W. Stallman of the U.S. Geological Survey to refer to him as “The Master of Radial Flow.” Hantush's numerous scientific publications contributed greatly to the present theories of flow in leaky aquifers, unconfined aquifers, and anisotropic aquifers. He derived the mathematical equations of flow to fully and/or partially penetrating wells in such aquifer systems, and devised methods for the analysis of pumpingtest data to determine their hydraulic properties. He was not only a researcher, but also a practicing hydrologist, deriving the equations he needed to solve practical problems.
