Please kindly disseminate to your colleagues who may be interested to attend. ABSTRACT Over the last 100 years, much research work has been done to obtain insight into the fundamentals of bed stability and bed movement. The mechanics of sediment transportt is, however, complicated by the fact that the interaction between flow and sediment on a bed is complex and that there is only limited knowledge of the mechanism of entrainment of bed material. This workshop will expose some new research as well as on implications of sediment transport i.e. scour. ABOUT the speaker Prof. Subhasish.Dey, Indian Institute of Technology, Kharagpur, India "Turbulence in mobile-bed streams" Subhasish Dey is currently Professor and Brahmaputra Chair of the Department of Civil Engineering, Indian Institute of Technology (IIT), Kharagpur, where he teaches free surface flow, sediment transport and turbulent fluid flow in graduate level. He has offered short courses on turbulence, sediment transport and scour in different universities of various countries. He was awarded PhD in the area of scour at bridge piers from the IIT Kharagpur in 1992. Presently, he is involved in studying turbulence in open-channel flows over sediment beds, turbulence induced secondary currents, etc. His general areas of research interests encompass sediment transport, scour, open-channel hydraulics, seepage effects on flow and sediment, coherent motion in turbulent flow and turbulent boundary-layer. He has published more than 110 research papers in journals. He is serving as Associate Editor for the Journal of Hydraulic Engineering, Sedimentology, Acta Geophysica, Journal of Hydro-Environment Research, International Journal of Sediment Research, Journal of Numerical Mathematics and Stochastics, etc. He is a council member of the World Association for Sedimentation and Erosion Research (WASER), Beijing. Prof. Chiew Yee Meng, Department of Civil and Environmental Engineering, NTU, Singapore “Failure of Houfeng Bridge - the curse of scour” Dr Chiew joined the Nanyang Technological University in June 1986 after completing his under-graduate and postgraduate education at the University of Auckland. After receiving his Bachelors Degree with first class honours in 1981, he proceeded directly to his doctoral research in the area of sediment transport. He completed his doctoral dissertation in 1985 and worked in the industry for a while before joining the academic world. He currently is a professor in Civil and Environmental Engineering. Presently, he is an Associate Editor of the Journal of Hydraulic Engineering, American Society of Civil Engineers (ASCE); the coordinator of a sub-group on scour at foundation within the Technical Committee 33 (TC-33) of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE); and a Committee Member of the Fluvial Hydraulics Section of the International Association of Hydraulic Research (IAHR). He has had more than 25 years of research experience in many aspects of fluvial, hydraulic, coastal and offshore engineering. His particular research interest is in the area of erosion, sediment transport and turbulence. In addition to his research activities, Dr Chiew provides extensive consulting services to the engineering industries, both internationally and in Singapore. He was the Chairman of the 2nd International Conference on Scour and Erosion (ICSE-2) that was held in Singapore in November 2004. Dr. Mamta Jain, DHI, Singapore “Suspended Sediment Plumes: Quantitative Comparison of Visual Impact and Remote Sensed Data” Dr. Jain has over eight years of experience in hydrodynamics and sediment transport modelling including the bed morphology and coastal processes, dredging and spill modeling and related Environmental Impact Assessment (EIA). She finished her PhD in wave induced resuspension of shallow mud bottoms at University of Florida with Dr Robert Dean and Dr Ashish Mehta. Dr. Jain's research project experience inlcudes extensive lake dynamics studies related to sediment resuspension, dredging spills, water quality and eutrophication. Project experience includes renowned international projects, research projects with the US University, US and Singapore State and Federal government. She has published her work in renowned journals such as ASCE Coastal Engineering Handbook, Continental Shelf Research and Journal of Coastal Research. Assoc Prof. Cheng Nian Sheng, Department of Civil and Environmental Engineering, NTU, Singapore Dr. Cheng Nian-Sheng is an Associate Professor in the School of Civil and Environmental Engineering. He previously worked as a Research Engineer at Nanjing Hydraulic Research Institute and an Assistant Research Professor at the Technical University of Denmark. His research interests include hydraulics and sediment transport, with special emphasis on particle-flow interactions and their applications in environmental and river processes. Prof Cheng has published more than 60 journal papers. He is the recipient of Scientific and Technological Achievement (1992, 2nd Class), Ministry of Transportation, China; and The Karl Emil Hilgard Hydraulic Prize (2005), American Society of Civil Engineers, USA. About NEWRI Launched in 2008, NEWRI represents NTU’s efforts over the last two decades to be a committed and active participant in Singapore’s Environmental and Water Technology (EWT) research and development landscape. Through NEWRI, the university aims to groom talent and provide EWT leadership, supporting Singapore’s pursuit of sustainable urban centre status. The NEWRI ecosystem offers a contiguous value chain of research, translation, development, and application that enables close collaborations with industry and community. It is represented by the core interests and activities of its 8 members which include four centres of excellence supported by EWI/EDB, a research group, a NTU company, a philanthropic initiative and a Master’s programme in environmental science and engineering. These NEWRI entities are inter-disciplinary and have activities which are inter-institutional. About DHI-NTU Centre Through an integrated approach, encompassing both research and education, DHI-NTU Centre strives towards a sustainable long-term conservation of environment while improving the quality of life for all. The Centre was jointly established by DHI Singapore (DHI) and NTU in October 2007, with support from the Environment & Water Industry Development Council (EWI). It is an inter-disciplinary research and training centre for the water & environment industry in Singapore. The centre works towards development of environmentally friendly solutions, and tools and technologies to support a sustainable ecology.
