Keynote Speakers

  • Bruce W. Melville, The University of Auckland, Auckland (New Zealand)

Bruce_Melville2Professor Bruce Melville is Professor of Civil Engineering at the University of Auckland. He is a founding member of the Centre for Infrastructure Research and is Associate-Editor of the (ASCE) Journal of Hydraulic Engineering, has served on local and international research committees, and has been a member of many tribunals for water consent hearings. He received the 2002 ASCE Hydraulic Structures Medal, in recognition of his contributions in the field and was elected to fellowship of the Royal Society of New Zealand in 2006. In 2007, he received the R.J. Scott Medal from RSNZ for his research contributions and in 2012 he received the Dobson Supreme Technical Award in Transportation Infrastructure. In 2011, he was promoted to Distinguished Fellowship of IPENZ and was awarded a Hood Travelling Fellowship. 

In his keynote "Local scour at hydraulic structures", he will present recent research findings related to local scouring, where the relation between the depth of local scour and its dependent parameters will be discussed. An emphasis is given to the underlying physics of the process of local scour but also on limitations in knowledge of the processes. The keynote focuses on dependent parameters describing the flood flow and bed sediment characteristics, the geometry of the hydraulic structure and the rate of development of local scour.

 

  •  David M. Paterson, University of St Andrews, St Andrews (UK)

David_PatersonProfessor David M. Paterson is Professor of Coastal Ecology at the University of St Andrews, Scotland. He is also Executive Director of the Marine Alliance for Science and Technology for Scotland (MASTS), a national organisation promoting interdisciplinary marine science, and is a member of Marine Scotland’s Science Advisory Board. In terms of research, he directs the Sediment Ecology Research Group at the Scottish Oceans Institute whose work involves biodiversity, ecosystem function and ecosystem service relationships, global change biology and the effects multiple stressors (acidification, temperature and hypoxia). He has a long record of examining interaction between physical drivers and the biologic mediation of depositional habitats, developing new techniques to research these interactions, working in the laboratory and in the field.

In his keynote address “Form, function and physics” he will assess the state of our knowledge of how organism and flow interact, discussing the ecological and evolutionary concepts of niche construction, and classical and cooperative ecosystem engineering against a background of the recent research on the physical and biological coupling in aquatic ecosystems.

 

  •  Weiming Wu, Clarkson University, Potsdam, N.Y. (USA)

Weiming_WuDr. Weiming Wu is Professor at Clarkson University, NY, USA. His research interests include sediment transport in rivers, estuaries and coastal waters; surge and wave attenuation by vegetation; dam/levee breaching; and pollutant transport. He has developed several empirical formulas for sediment settling, deposit porosity, movable bed roughness and nonuniform sediment transport, as well as a number of one-, two- and three-dimensional computational models for free surface flows, sediment transport, pollutant transport, aquatic ecosystems, vegetation effects and dam/levee breaching. He published a book "Computational River Dynamics" through Taylor & Francis, UK in November 2007. He is a Fellow of ASCE, and a member of IAHR and WASER. He currently serves as an Associate Editor for ASCE Journal of Hydraulic Engineering.

In his keynote "Advances and Challenges in Mixed Cohesive/Noncohesive Sediment Transport Research", Dr. Wu will present 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 (<~0.01 mm 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 noncohesive 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, uplands, etc.
