Coastal Engineering - Numerical Modelling Solutions
The Water Research Laboratory (WRL) is located at Manly Vale on Sydney’s Northern Beaches, and is part of the School of Civil and Environmental Engineering at the University of New South Wales (UNSW). WRL undertakes coastal engineering activities through a dedicated projects team, where full time project staff undertake studies and offer expert advice to industry and government. WRL employs a vast range of numerical (computer) models in its projects and research efforts. These software programs include hydrodynamic models, water quality models, sediment transport models, wave transformation models, rainfall and runoff models, and groundwater models. These programs are run on a local network of computers consisting of PC’s and UNIX work stations.

Key WRL Personnel
Brett Miller: Brett is the Manager of WRL and also an experienced and skilled numerical modeller. He has been undertaking RMA modelling projects since 1992 when he commenced work on the 3D simulation of the Sydney Deepwater Outfalls. In 1995 he was appointed the Section Leader for Environmental Modelling at WRL and was responsible for the technical direction and marketing of modelling activities. Brett has undertaken hydrodynamic and water quality modelling on over 20 major studies in locations including Australia, Hong Kong, Singapore, Philippines and New Zealand. Studies have varied in size from small pilot modelling exercises to large studies, such as the Western Waters of Hong Kong that involved 3D modelling of hydrodynamics and water quality in highly stratified conditions, with 5 engineers full time for 18 months. Brett has also been strongly involved with the hydraulic design and near field prediction of outfall performance with recent projects including: Waimakariri Outfall (NZ), Christchurch Outfall (NZ), Shellharbour Outfall and the proposed Perth Desalination Outfall. Brett holds a BE in Civil Engineering, a BSc in Computer Science and a MEngSc in Water Engineering.
James Carley: James is a Senior Project Engineer at WRL. He has over 17 years experience in coastal engineering, specialising in coastal processes, coastal hazards and physical modelling. James holds a MEngSc majoring in Coastal Engineering and Physical Oceanography, and was the 2007-08 Chair of the NSW Maritime Panel of the Institution of Engineers Australia. James is one of Australia’s foremost experts in the practical application of coastal process models and has extensive experience with the best currently available numerical and analytical models from around the world. James has undertaken detailed studies of beaches throughout Australia, the South Pacific, South-East Asia and the Middle East. These studies have involved a review of historical events, prediction of future response to major storms, climate change and sea level rise, and beach response to structures. The techniques used include detailed historical analysis of beach profile survey data, computer/numerical modelling, and physical laboratory modelling of beach shape and the response of structures to waves. James has authored more than 100 WRL Technical Reports and more than 20 papers for state, national and international conferences. He has been a surfer, surf life saver and ocean swimmer for more than 30 years, which allows him to closely understand coastal processes and community issues.
Dr William Glamore: William is a Senior Research Fellow at WRL. William has a BSc in Environmental Science and a PhD in Civil/Environmental Engineering. William has been with WRL since 2003 and has managed and undertaken several large studies during this time. His primary fields of interest are related to estuarine hydrodynamics and water quality including restoration of estuarine environments, acid sulphate soils, coastal wetlands, boat wake waves, outfall hydraulics and field testing, and related physical and numerical models. While William’s work is particularly focused on estuarine environments, his practical experience crosses all water related environments including reservoirs, wetlands, groundwater and coastal settings.
