Aly I. El-Kadi is a Professor of hydrology in the department of Geology and Geophysics. His teaching and academic interests focus on hydrogeology and groundwater modeling. Professor El-Kadi is also a researcher at the Water Resources Research Center where his research interests cover a wide range of topics including climate change effects on water resources sustainability, numerical modeling, and modeling multiphase flow and transport of hydrocarbons.

Professor El-Kadi is the Associate Director (2000-2018) of the Water Resources Research Center, which serves the state of Hawaiʻi and other Pacific islands by researching water-related issues distinctive to the region. He is also a member of the ʻIke Wai leadership team, a National Science Foundation (NSF) Experimental Program to Stimulate Competitive Research (EPSCoR) project that aims to increase understanding of Hawaiian island hydrology to provide improved data for decision-making tools that address the challenges to water sustainability from climate variability, increasing population demands, and water contamination. His current research for the project covers goundwater modeling and studying the increasing stress placed on Hawaiʻi’s aquifers due to factors associated with population growth, economic development, and climate change. Professor El-Kadi’s work expands beyond Hawaiʻi to include projects in American Samoa and Guam where he is researching real-time optimization of irrigation scheduling for farmlands through funding provided by the USDA Natural Resources Conservation Service.

Professor El-Kadi earned his Ph.D. in Groundwater Hydrology from the School of Civil and Environmental Engineering at Cornell University in Ithaca, New York, an M.S. in Surface Water Hydrology from Ain Shams University, and a B.S. in Fluid Mechanics and Hydraulics from Ain Shams University located in Cairo, Egypt.
