Flow through Heterogeneous Geologic Media

Tian-Chyi J. Yeh is a professor in the Department of Hydrology and Water Resources at the University of Arizona, a joint professor in the Department of Resources Engineering at the National Cheng Kung University, Taiwan, Republic of China, and an adjunct professor in the Department of Earth and Environmental Sciences at the University of Waterloo. He also holds an Oversea-Renowned Professorship from the Chinese Department of Education at Jilin University, China. Dr Yeh has more than 30 years' experience with stochastic/numerical analysis and laboratory/field investigations, as applied to heterogeneity effects on flow and solute transport in saturated and unsaturated geologic media. He has published more than 120 research articles and chapters in peer-reviewed journals and books.

Raziuddin Khaleel is a senior hydrogeologist at INTERA, Inc. and an adjunct professor in the Department of Civil and Environmental Engineering at Washington State University, Richland. He has 48 years of experience in the areas of numerical modeling and groundwater, vadose zone, and surface water hydrology. Dr Khaleel has taught numerous graduate and undergraduate courses in groundwater, fluid mechanics, hydrology, groundwater hydraulics, numerical modeling, and vadose zone hydrology at Washington State University; the New Mexico Institute of Mining and Technology, Socorro; and the Indian Institute of Technology, Roorkee. He has published more than 50 refereed journal articles, several book chapters, and numerous papers in symposium proceedings. Dr Khaleel also served as UNESCO and UNDP Consultant to the government of India; the School of Hydrology, Indian Institute of Technology; and a number of companies dealing with nuclear waste repository programs in Taiwan and Japan.

Kenneth C. Carroll is an assistant professor in the Department of Plant and Environmental Sciences and the Water Science and Management Graduate Program at New Mexico State University. His research has focused on hydrogeology, contaminant transport, and groundwater remediation. Dr Carroll has published more than 25 refereed journal articles and symposium proceedings papers. At NMSU, he supports the environmental and soil science focus areas, and his teaching and research background and interests cover a broad range of areas that pertain to the coupling of hydrobiogeochemical processes that mediate exchange of water and chemicals between the hydrosphere, lithosphere, and biosphere.
