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.
