Accurate forecasting of coastal recession due to sea level rise is required for planning and the design of coastal defences, but the existing method is widely disputed. With collaboration with world leading research partners, this study will perform unique laboratory experiments to determine the vulnerability of Australian beaches to sea level rise and to test environmentally sustainable measures to increase their resilience. The research will address longstanding uncertainties and significantly enhance the ability of communities to plan for a changing climate. The project will deliver new data and models of immediate benefit to professional engineers to enable robust engineering decisions which enhance the safety of coastal communities.Read moreRead less
Poro-elastic, single domain model of wave-induced transport and transformation of pollutants in coastal sediments. The sediments in many bays and estuaries in Australia are contaminated by pollutants due to discharge of waste from the river, groundwater or/and ocean outfall. Most previous research has had a multi-domain approach and have ignored the wave-dirven advective flow and effects of soil behaviour in coastal sediment. In this study, we will couple the procedure of pollutant transport ne ....Poro-elastic, single domain model of wave-induced transport and transformation of pollutants in coastal sediments. The sediments in many bays and estuaries in Australia are contaminated by pollutants due to discharge of waste from the river, groundwater or/and ocean outfall. Most previous research has had a multi-domain approach and have ignored the wave-dirven advective flow and effects of soil behaviour in coastal sediment. In this study, we will couple the procedure of pollutant transport near the sediment-water interface by a single domain approach, and link wave-dirven advective flow and contaminant in marine sediments. The research outcomes will provide a better prediction of the transformation behaviour of pollutants in contaminated sediments.Read moreRead less

This Research Hub will harness the strengths of data-based and physics-based sciences to transform the operation of Australia’s offshore energy infrastructure. This essential research will create, use and embed observations of past and ongoing activity to engineer tools and approaches necessary to enhance our understanding of the offshore environment, optimise critical operations for existing facilities (including installation and maintenance), and efficiently design future infrastructure. The integrated multidisciplinary approach will not only help Operators achieve high productivity through low downtime and optimised maintenance, but also demonstrate, in research and industry, the transformative potential of digital engineering.Read moreRead less
Modelling of sand wave migration and its interaction with pipelines. The movement of sand due to sand waves can interfere with marine structures such as pipelines and cables on the seabed. It may also cause free spans of pipelines, with potentially serious consequences. Most previous research has considered sand wave propagation and the stability of pipelines as separate problems. In this project, we propose a coupled analysis of sand wave migration and its interaction with pipelines through mat ....Modelling of sand wave migration and its interaction with pipelines. The movement of sand due to sand waves can interfere with marine structures such as pipelines and cables on the seabed. It may also cause free spans of pipelines, with potentially serious consequences. Most previous research has considered sand wave propagation and the stability of pipelines as separate problems. In this project, we propose a coupled analysis of sand wave migration and its interaction with pipelines through mathematical and numerical modelling. The theoretical work will be supported by laboratory experiments. The resulting research will provide a better understanding of sand wave migration, beach profiles and the stability of pipelines.Read moreRead less
Coupling models for ocean waves, groundwater and porous seabeds interaction. The ocean waves, groundwater flow and porous seabeds interaction problem is vital for erosion control, saltily and biological activities in coastal regions. Most previous research has investigated the problem from individual aspects, rather than a coupling concept. In this study, we will develop advanced theoretical models for procedures of waves propagation, water table fluctuations and soil behaviour in a porous seabe ....Coupling models for ocean waves, groundwater and porous seabeds interaction. The ocean waves, groundwater flow and porous seabeds interaction problem is vital for erosion control, saltily and biological activities in coastal regions. Most previous research has investigated the problem from individual aspects, rather than a coupling concept. In this study, we will develop advanced theoretical models for procedures of waves propagation, water table fluctuations and soil behaviour in a porous seabed, and couple them in a model. A series of experiments will be conducted for the verification of the theoretical findings. The research outcomes will provide a better understanding of the interaction between ocean wave, groundwater flow and porous seabeds.Read moreRead less

This project aims to establish a Coastal Engineering Research Field Station (CERFS) with instrument modules for measuring waves, tides, currents, seabed and beach profiles and sediment characteristics. There are critical knowledge gaps in the understanding of coastal processes, including the effects of climate variability and change, and a need to generate long-term data-sets for calibration of coastal models against Australian conditions. The coastal process data obtained will lead to improved models, management strategies and design guidelines improving techniques to address coastal infrastructure design, beach management strategies and impact assessment to meet the challenges of future major coastal development. This will help decision-makers to reduce the risk to coastal communities, coastal ecosystems and maritime operations from extreme storms, climate change, infrastructure development and urbanisation.Read moreRead less

This project expects to generate new knowledge on how flow slides are triggered, propagate inland and undermine structures. Expected outcomes include globally applicable novel models and management approaches developed by an interdisciplinary team of coastal and geotechnical engineers and coastal geomorphologist using innovative data. This is likely to provide significant benefits for planning and managing structures along coasts and bays against destructive flow slides. The project will enable the design and implementation of coastal works to protect existing structures against flow slides risks emerging with rising sea level.Read moreRead less
Bed shear stress on beach sediment and coastal structures under wave run-up. The aim of this work is to obtain critical new information about the way waves interact with the coast and the damage they can cause to beaches and coastal protection structures. This new data will provide the basis for improved predictions of coastal erosion and better coastal engineering design in the face of sea-level rise and climate change.
