Physical and Numerical Modelling of the Interaction of Extreme Waves with the Coast. Prof. Alistair Borthwick


Engineers are required to assess the run-up of beaches and overtopping of coastal structures due to extreme waves. This presentation describes numerical and physical model studies of the run-up and overtopping of solitary waves and focused wave groups at a plane beach (with and without a seawall). The physical model data are taken from various sources, including the U.K. Coastal Research Facility. A mapped paddle Boussinesq-shallow water solver will be described, along with details of its verification and validation. It will be shown that the numerical model gives satisfactory estimates of run-up and overtopping volumes in comparison with the experimental data – in all cases for first-order paddle correction. Results from the numerical model will then be used to highlight the need for second-order paddle correction, and the rather major ramifications for coastal overtopping tests discussed.

Brief CV

In October 2011, Alistair Borthwick took up the position of Professor of Civil and Environmental Engineering at University College Cork, Ireland. Prof. Borthwick was previously a Professor of Engineering Science at the University of Oxford, where he worked for 21 years. He remains an Emeritus Fellow at St Edmund Hall Oxford. Prof. Borthwick has more than 30 years' experience in civil, coastal, and offshore engineering. He was a member of the design team of the Hutton Tension Leg Platform, which won the Queen's Award for Technological Achievement in 1984. Prof. Borthwick's research interests include shallow water-sediment flows, flood risk, coastal processes, offshore engineering, and marine renewable energy. He has co-authored more than 100 papers in peer-reviewed journals, and supervised more than 30 doctoral students to completion. In 2005, Prof. Borthwick was awarded a DSc by the University of Oxford for his sustained research in environmental fluid mechanics.
