This book focuses on the fundamentals of sediment transport in surface waters. It covers sediment properties, open channel flows, sediment particle settling, incipient motion, bed forms, bed load, suspended load, total load, cohesive sediments, water-sediment two-phase flows, hyperconcentrated flows, debris flows, wave-induced sediment transport, turbidity currents, and physical modeling. Besides the primary context of river sedimentation, this book extensively covers sediment transport under coexisting waves and currents in coasts and estuaries, hyperconcentrated and debris flows in rivers, as well as turbidity currents in lakes, reservoirs, channels and the ocean. It includes a chapter on the water-sediment two-phase flow theory, which is considered the basis of many sediment transport models. It introduces some special topics emerged in recent years, such as transport of mixed cohesive and noncohesive sediments, transport of biofilm-coated sediments, and transport of infiltrated sand within gravel and cobble beds. The text merges the classical and new knowledge of sediment transport from various sources in English and non-English literature. It includes important contributions made by many scientists and engineers from all over the world. It balances the breadth, depth, fundamental importance, practical applicability, and future advancement of the covered knowledge. It can be used as a text and reference book. The chapters are arranged in a sequence for teaching purposes. Certain homework problems are prepared, which also highlight the important topics for instructors to select. Solutions to homework problems are available from the author by request.

Weiming Wu is the James K. Edzwald Professor of Water Engineering at Clarkson University, NY, USA. Dr. Wu earned his Ph.D. from Wuhan University of Hydraulic and Electric Engineering, China in 1991. He was a Lecturer/Associate Professor at his Alma Mater in 1991-1995, a Research Fellow of 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 a 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 ASCE, and a member of IAHR and WASER. He served as an Associate Editor for the International Journal of Sediment Research in 2008-2010 and for ASCE Journal of Hydraulic Engineering in 2010-2019, as well as the Chair for ASCE Computational Hydraulics Committee (2010-2012), ASCE Task Committee on Dam/Levee Breaching (2009-2012), and ASCE Sedimentation Committee (2016-2018). He currently serves as a council member for WASER.
