Yafei Jia 教授简介：
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. As a hydraulic engineer, he worked on sedimentation problems of the Yellow River. 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. He joined the NCCHE in 1990 as a Post-Doctoral Research Associate. He was promoted to Research Assistant Professor in 1994, promoted to Research Associate Professor in 2000，and promoted to Research Professor in 2005 . In the past eighteen years, he has been involved in the development, verification and application of a variety of two and three dimensional numerical models capable of simulating unsteady, turbulent free surface flow, and sediment transport problems. Among these models, the near field 3D turbulent flow and erosion process is one of the most complex phenomena he has successfully modeled. Dr. Jia has published over 50 publications including technical papers and reports.
美国国家计算水科学与工程中心简介：
The Center for Computational Hydroscience and Engineering (CCHE) was established in 1982, as a research unit in the School of Engineering at The University of Mississippi, by the State of Mississippi's Institutions of Higher Learning Board of Trustees. Due to international recognition and national prominence, The University of Mississippi decided in 1999 to rename CCHE to NCCHE (National Center for Computational Hydroscience and Engineering), to broaden its activities and accelerate its progress.
NCCHE has made significant contributions, which have earned the Center international recognition, to the advancement of computational modeling and simulation of free surface flows, soil erosion, sediment transport and morphological processes in streams, reservoirs, and channel networks in watersheds. NCCHE has been invited by prestigious professional societies to host several major international conferences and has welcomed many renowned visiting scientists. Dr. Sam S. Y. Wang, the Director of NCCHE, has been invited to chair conferences and to deliver keynotes and special lectures at professional meetings and research institutes in more than 30 countries on six continents.
Supported by several federal agencies in the field of hydroscience and engineering, NCCHE was awarded a Congressional appropriation of approximately $1,000,000 annually with a mandate to develop, verify, refine, validate, and apply state-of-the-art computational simulation models, which are applied in cooperation with several federal agencies to the conservation of water and soil resources and to the protection of the quality of the environment and ecology. During a budget tightening period, these cost-effective research and engineering tools are in high demand. These tools could be used to achieve agencies' responsibilities with reduced financial resources.
