Autorenporträt

Dr. Weiming Wu is James K. Edzwald Professor of Water Engineering at Clarkson University, NY, USA. Dr. Wu earned his PhD from Wuhan University of Hydraulic and Electric Engineering, China in 1991. He was Lecturer/Associate Professor at his alma mater in 1991-1995; Research Fellow of the Alexander von Humboldt Foundation at the Institute for Hydromechanics, University of Karlsruhe, Germany in 1995-1997; and a faculty member at the National Center for Computational Hydroscience and Engineering of the University of Mississippi in 1997-2013. His research interests include fundamental sediment transport; hydro- and morphodynamics in rivers, estuaries, coastal waters and uplands; surge and wave attenuation by vegetation; interaction between surface and subsurface flows; free surface flow and sediment transport modeling; dam/levee breach and flood modeling; and water quality and aquatic ecosystem/ecotoxicology modeling. He has developed a suite of computational models for flow, sediment transport, pollutant transport, and aquatic ecology in riverine and coastal waters. He authored the book Computational River Dynamics, published through Taylor & Francis, UK in November 2007. In addition, he has published more than 150 articles on journals and conferences. He received a Best Paper Award in 2007 from the World Association for Sedimentation and Erosion Research (WASER). He is a fellow of American Society of Civil Engineers (ASCE) and a member of the International Association for Hydro-Environment Engineering and Research (IAHR). He served as Associate Editor for the International Journal of Sediment Research in 2008-2010 and for the ASCE Journal of Hydraulic Engineering in 2010-2019, and was Chair of the ASCE Computational Hydraulics Committee (2010-2012), the ASCE Task Committee on Dam/Levee Breaching (2009-2012), and the ASCE Sedimentation Committee (2016-2018). He currently serves as Vice President for WASER.
