Dr. Mustafa S. Altinakar is currently the Director and Research Professor at the National Center for Computational Hydroscience and Engineering (NCCHE) of the University of Mississippi. Dr. Altinakar obtained his Ph.D in Hydraulics at the Laboratoire de Recherches Hydrauliques (LRH), Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland in 1988, and his M.S (1980) and B.S. (1978) degrees in Civil Engineering from the Middle East Technical University, Ankara, Turkey. Before joining the NCCHE in December 2002, he was the Acting Director of LRH, EPFL, Switzerland (2001-2002). From 1997 to 2001, he was the Head of the Fluvial Hydraulics Section of LRH-EPFL. During the period 1989-1997, Dr. Altinakar worked as a Senior Design Engineer and Project Manager for a large Swiss Consulting Company, Bonnard and Gardel Consulting Engineers Ltd and took part in various large-scale engineering projects in Europe and Africa. In this period, he continued to work as a part time Research Associate at LRH-EPFL and taught courses. His fields of specialization and research interests include fluvial hydraulics and its environmental aspects, sediment transport and local scour, flood simulation and management, diffusion and dispersion in waterways, transport and fate of contaminants, stratified flows, computational fluid dynamics, integrated watershed management, optimization and decision support systems, and design of hydraulic structures. His publications include 2 books, more than 70 journal and conference papers, several articles for online encyclopedias. He has been invited to deliver keynote lectures, short courses at various universities and leading research institutes around the world. He is a member of the ASCE (American Society of Civil Engineers), IAHR (International Association of Hydro-Environment Engineering and Research), AGU (American Geophysical Union), ASFPM (Association of State Flood Plain Managers) and ASDSO (Association of State Dam Safety Officials). He serves as the Chair of the Standing Committee on Global Water Issues of the International Flood Initiative (IFI) of UNESCO/IAHR, Vice Chair of the IAHR Task Committee on Fluvial Hydraulics, member of the Fluids Committee of the ASCE. He is currently the PI for two projects for developing 2D flood simulation models and GIS-based decision support systems for flood mitigation, management. The numerical models developed in these projects are currently being used by various federal and state agencies.

Dr. Yafei JiaResearch Professor and Assistant Director of Basic Research | Office: (662) 915-7783
Dr. Yafei Jia received his B.S and M.S. in Physical Geography at Beijing University in 1982, and the Institute of Geography, Chinese Academy of Science in 1985. He received his Ph.D. in the Department of Geography, University of Manchester, UK, in 1990. He was the first to propose the “minimum Froude number theory” to interpret the stream channel adjustment process.

Dr. Jia joined the National Center for Computational Hydroscience and Engineering, the University of Mississippi, in 1990 as a Post-Doctoral Research Associate. He was promoted to Research Assistant Professor (1994), Associate Professor (2000) and Professor in 2006. In the past twenty years at NCCHE, he has been the major developer of the two and three dimensional computational models: CCHE2D and CCHE3D. These two free surface turbulent flow models have been developed, verified, validated, and refined using many sets of analytical solution, physical model data and widely applied to research and engineering projects. With these models, detailed 3D turbulent flow structures and general flow patterns in channels, lakes, reservoirs, estuaries and around hydraulic structures can be modeled successfully. In addition to free surface flow hydrodynamics, capabilities such as sediment transport, bank erosion, water quality and pollutant transport, etc., are developed in these models. To enhance the efficiency of applications, these capabilities are integrated and operated with a user friendly Graphic User Interface. Dr. Jia has published over 100 technical papers in the areas of computational model development, verification, validation and applications, as well as numerous technical reports of engineering projects. Recently, his research group has extended the capabilities of numerical models to simulate flood associated phenomena, including dam break flows, dam break/levee breaching processes, pollutant transport due to floods, etc. A levee closure simulator has been developed to simulate an engineering practice in an attempt to close a breached levee with sandbags and/or rocks.
