KEYNOTE SPEAKERS     Lu Yaoru               Lu Yaoru, expert of karst and hydro-engineering and environmental geology, was born in 1931 in Fuzhou , Fujian Province. He studied at the Department of Geology of Tsinghua University in 1950, then turned to the Department of hydro-engineering geology of Beijing College of Geology in 1952, and graduated ahead of time in 1953. Now he is the Professor of Chinese Academy of Geological Sciences and part-time Professor of Tongji University etc. He also is the member of Expert Committee of the National Commission for Reduced Hazards, and the Member of the National Environmental Consultative Committee, and he leads the Joint Research Center of Urban Environment and Sustainable Development, Ministry of Education, People’s Republic of China . Professor Lu has researched the Karst and related hydro-engineering and environmental geology for 53 years. He led and/or directed the researches and prospecting works of a series of water conservancy and water power constructions, which related to Yangtze River, Yellow River, Zhujiang River, Huaihe River etc. river systems, such as Sanxia (Three Gorges), Wujiangdu, Xin’an Jiang etc. projects; he has also directed the investigations and researches of communication, cities and towns etc. constructions; and he also made the contribution for the development of karst regions by studying the karst geo-ecology and for prevention and treatment of geo-hazards. He has found a set of theories related to karst developmental rules and engineering impacts. For his outstanding contributions on karst researches, he got the prized name “Karst Lu”. His important work are: “Karst in China---LandscapesŸTypesŸRules”，”Karst in China”, Research on Evolutions of Karst Hydro-geological Environments and their Engineering Impacts, Geo-ecology and Sustainable Development—Developmental Ways for karst regions of Southwest China and Neighbor Regions”, publications and a series of karst maps as well as about one hundred papers. He got the awards related to National Sciences Conference in 1978, Geological Sciences and National Excellent Scientific and Technological Publications, and he got the J.S. Lee Honors Prize for Geological Sciences in scientific Research 1999. He was elected the Academician of the Chinese Academy of Engineering in 1997.          William K. Jones      Mr. Jones is a consulting hydrologist with Environmental Data in Warm Springs , Virginia .  He studies physical hydrology of surface and ground-water resources with an emphasis on areas underlain by carbonate (karst) aquifers.  He has studied karst areas across North America, France , Eastern Europe , China and Southeast Asia .  Mr. Jones is the author of over twenty papers on karst hydrology and water tracing.  He is the author of the “Karst Hydrology Atlas of West Virginia” (1997) and served as the guest editor for a special issue of the National Speleological Society Bulletin on water tracing using fluorescent tracers (1984).  He wrote the chapter on water tracing for the “Encyclopedia of Caves” (2005). He is the first author of “Recommendations and Guidelines for Managing Caves on Protected Lands” (2003) prepared for the U.S. Department of the Interior. Mr. Jones holds a BSF degree in Forest Management from West Virginia University (1973) and an MS degree in Environmental Science (Hydrology) from the University of Virginia (1989).  He was an adjunct professor of hydrology at the American University , Washington , DC and is a director of the Karst Waters Institute and a fellow of the National Speleological Society.
Prof. Dr. Martin Sauter
Professor Sauter studied geology at the University of Tübingen and hydrogeology at the University of Birmingham (M.Sc. 1981). After various research and consulting activities in the area, he returned as an assistant at the Department of Applied Geology and the University of Tubingen, where he received his PhD in 1991 on a theme for the modeling and characterization of karst aquifers. From 1998 he served as professor of hydrogeology for groundwater research at the University of Jena. Since 2002 he is Professor of Applied Geology at the University of Göttingen. His research interests focus on characterization and modeling of fracture and karst aquifers, mining problems, and to study the behavior of organic pollutants.
