Panel discussion 
PIANC’s Inland Navigation Commission (InCom) will organise the virtual conference ‘Saltwater Intrusion in Inland Waterways’ on 10 December 2021. 

The 2-hour session will cover two parts featuring six presentations dealing with PIANC WG-report 198 on ‘Saltwater Intrusion in Inland Waterways’ and will conclude with a Q&A-session. This conference will be recorded. 

WORKSHOP ORGANISING COMMITTEE:
  • Tom O’Mahoney, Chairman of PIANC InCom WG 198

SPEAKERS:

Tom O’Mahoney is a Senior Hydraulic Researcher at Deltares (previously Delft Hydraulics) in Delft, the Netherlands. Since 2014 he has worked there on projects involving detailed flow around hydraulic structures such as shipping locks, weirs and sluices, focusing on numerical modelling and comparisons with experimental data gathered in the Deltares laboratory. The projects have involved assessing the levelling systems of two large new shipping locks at IJmuiden and Terneuzen in the Netherlands and studies of salt intrusion through shipping locks and flushing sluices in the Netherlands and abroad (Belgium and Panama). He is the Chair of the PIANC Working Group 198 on Saltwater Intrusion in Inland Waterways. Prior to Deltares he worked as a CFD research engineer and has a MSc in Hydrodynamics and PhD in Computational Fluid Dynamics from the University of Surrey in the United Kingdom.
 
Tom van der Wekken has been working for 45 years at Rijkswaterstaat, the Dutch executive organization of the Ministry of Infrastructure and Water Management. Rijkswaterstaat is responsible for constructing, operation and maintenance of the capital infrastructure for traffic, inland navigation and water management in the Netherlands. He was involved in many hydraulic engineering projects with a focus on density currents (at the connection between salt and fresh water). Recent projects in which he contributed are the deepening of the Rotterdam Waterway, salt intrusion into Amsterdam-Rijnkanaal induced by the New Sea Lock IJmuiden, and through the Haringvliet sluices. He retired from Rijkswaterstaat at the beginning of 2021.
 
Gary L Brown is a Research Hydraulic Engineer in the Coastal and Hydraulics Laboratory at the U.S. Army Engineer Research and Development Center (ERDC) in Vicksburg, Mississippi.  He received both his B.S. (1993) and M.E. (1995) in Civil Engineering from the University of Florida.  Since that time, he has worked at ERDC, in the development and application of multi-dimensional numerical models to investigate hydrodynamics, salinity, and sediment transport in estuaries and rivers. 
His past applied work has included salinity intrusion modeling for the Sabine-Neches Waterway Channel Deepening Project, investigations of the Colorado River Diversion in Matagorda Bay, Texas, coastal wetland restoration efforts in Biscayne Bay, Florida, and the restoration of salt ponds to coastal wetlands in South San Francisco Bay, among others. 
 
Frank Kösters, PhD, is head of the section ‘Estuary Systems I’ at the Federal Waterways Engineering and Research Institute (BAW) in Hamburg, Germany. He is responsible for providing consultancy and expert opinion services to the ministry of transport and infrastructure (BMVI) and the national water and shipping administration (WSV) relating to their waterways engineering tasks. In particular he is concerned with hydrodynamic and morphodynamic modelling studies as a basis for environmental impact studies for large infrastructure projects such as channel deepenings. His professional background is in numerical modelling of hydrodynamics and sediment transport in estuaries and shelf seas.
He holds a PhD in physical oceanography from the Christian-Albrechts-University in Kiel and an MSc in Applied Geophysics from the University of Birmingham university. Since 2008 he joined BAW working in hydraulic engineering in coastal areas.

Meinte Blaas, PhD, Senior policy advisor, Rijkswaterstaat the Netherlands. Mr Blaas works as senior advisor for the Dutch national water management authorities Rijkswaterstaat, part of the ministry of Infrastructure and Water Management. His professional focus is twofold: one is policy advice at strategic level regarding climate adaptation for sustainable management of fresh water resources under pressure from marine and groundwater salinization. The other is internal consulting and coordination of research and advisory projects on management of salinization-prone water bodies at a tactical level. This latter involves knowledge and capacity-building within Rijkswaterstaat and its partners to better understand the functioning of these water bodies. Model forecasting and hindcasting, monitoring and system analysis are key elements in his work. Mr Blaas holds a PhD in physical oceanography at Utrecht University and has previously been working for over fifteen years as researcher-consultant in various institutes on national and international projects concerning water quality, hydrodynamics and sediment transport.

William H. McAnally, Ph.D., P.E., D.NE, D.CE, F.ASCE, is a PIANC member and currently serves as Principal Water Resources Engineer at Dynamic Solutions, LLC, and Research Professor Emeritus at Mississippi State University. He was previously the Technical Director for Navigation Research and Chief of the Estuaries and Rivers Division at the U.S. Army Engineer Research and Development Center. His over fifty years’ experience in inland and coastal hydraulics, sedimentation, and waterborne transportation includes salinity intrusion investigations in Chesapeake Bay, Mississippi River, San Francisco Bay, and the Panama Canal. He and his wife, Carol, have four children and seven grandchildren.​​​​​​​
