Clarkson University Prof to Deliver Keynote Speech at International Symposium on River Sedimentation

Clarkson University Professor of Civil & Environmental Engineering Weiming Wu has been invited to give a keynote speech at the International Symposium on River Sedimentation.

Weiming WuHeld from Sept. 19 to 22 in Stuttgart, Germany, ISRS 2016 provides a forum for scientists, engineers and policy-makers to share information, exchange ideas and collaborate in the field of erosion and sedimentation processes.

Wu's presentation, "Advances and Challenges in Mixed Cohesive/Noncohesive Sediment Transport Research," will feature a state-of-the-art review of recent advances in laboratory experiments, field measurements and computational modeling of mixed cohesive/noncohesive sediment transport.

Noncohesive sediments move as individual particles, whereas cohesive sediments -- less than 0.01 millimeter in size -- usually erode and transport in flocs that consist of fine particles irregularly bonded by interparticle electrostatical forces and undergo continuous, dynamic aggregation and disaggregation. When cohesive and non-cohesive sediments are mixed, interactions between them play an important role, and the sediment mixture experiences much more complex erosion and transport processes. Researchers and engineers encounter significant challenges when dealing with such mixed sediments which widely exist in estuaries, coastal inlets, reservoirs, rivers and uplands.

As an associate editor for the American Society of Civil Engineers Journal of Hydraulic Engineering, Wu's research interests include sediment transport in rivers, estuaries and coastal waters; surge and wave attenuation by vegetation; dam and levee breaching; and pollutant transport.

He has developed several empirical formulas for sediment settling, deposit porosity, movable bed roughness and non-uniform sediment transport, as well as a number of one-, two- and three-dimensional computational models for free surface flows, sediment transport, pollutant transport, vegetation effects and dam and levee breaching. He published a book, Computational River Dynamics, in 2007.

Clarkson University educates the leaders of the global economy. One in five alumni already leads as an owner, CEO, VP or equivalent senior executive of a company. With its main campus located in Potsdam, N.Y., and additional graduate program and research facilities in the Capital Region and Beacon, New York, Clarkson is a nationally recognized research university with signature areas of academic excellence and research directed toward the world's pressing issues. Through more than 50 rigorous programs of study in engineering, business, arts, education, sciences and the health professions, the entire learning-living community spans boundaries across disciplines, nations and cultures to build powers of observation, challenge the status quo, and connect discovery and innovation with enterprise.
