Geo-hydrodynamic modelling and estuarine evolution. We have accumulated considerable knowledge of the geomorphology, sedimentology and hydrodynamics of estuarine systems in southeastern Ausralia. This project represents the first rigorous attempt to combine these diverse factors to provide a process-based mathematical model of long- to medium-term sedimentation that can be used for environmental management.

We have accumulated considerable knowledge of the geomorphology, sedimentology and hydrodynamics of estuarine systems in southeastern Ausralia. This project represents the first rigorous attempt to combine these diverse factors to provide a process-based mathematical model of long- to medium-term sedimentation that can be used for environmental management. To be predictive the model has to use documented changes in the sedimentation histories of different estuary types over the past 8000 years in order to predict their evolution over the next 1000 years. The models that are developed can be applied to estuarine systems both nationally and internationally.Read moreRead less
Hyper-accumulations of monosulfidic sediments: Exploring a biogeochemical extreme to resolve fundamental sulfur biomineralisation pathways. The hyper-accumulation of monosulfidic sediments has a directsocial, economic and environmental impact on communities in many parts of Australia, including highly valued wetland systems such as the Ramsar wetlands of the lower Murray Darling Basin and internationally recognised Peel-Harvey Estuary of WA. Maintenance dredging of these materials alone costs th ....Hyper-accumulations of monosulfidic sediments: Exploring a biogeochemical extreme to resolve fundamental sulfur biomineralisation pathways. The hyper-accumulation of monosulfidic sediments has a directsocial, economic and environmental impact on communities in many parts of Australia, including highly valued wetland systems such as the Ramsar wetlands of the lower Murray Darling Basin and internationally recognised Peel-Harvey Estuary of WA. Maintenance dredging of these materials alone costs the nation millions of dollars annually. The hyper monosulfidic sediments are also linked to severe environmental impacts. This project will inform how these materials develop and accumulate. This new knowledge will be of immediate relevance for the management of eutrophic estuaries.Read moreRead less
