Toward national coastal water quality forecasts in Australia

Abstract:

Many of the issues surrounding marine management of the coastal zone relate to water quality. If numerical models are to assist in management strategies revolving around compliance and response, it is essential that the models are capable of predicting water circulation, sediment transport and biogeochemical processes. CSIRO Oceans and Atmospheres have taken the first steps in developing such systems through the eReefs partnership, where models spanning circulation, sediment transport and biogeochemistry have been constructed for the Great Barrier Reef (GBR) at 4km and 1km scales, capable of forecasts out to 4 days, within which nested high resolution models (RECOM) can capture fine scale estuary, bay and reef dynamics. These models explicitly account for freshwater, sediment and nutrient inputs from catchments and subsequently predict the response of the GBR lagoon. In this presentation we demonstrate the performance and products of the multi-disciplinary eReefs models, and project on how such a system could be developed and applied nationally to allow coastal managers a real-time 3D view of water quality around the Australian coastline.

About the Association

The Australian Coastal Society (ACS) was initiated at the Coast to Coast Conference in Tasmania in 2004. The idea was floated as a means for those interested in coastal matters to communicate between conferences and where possible take resolutions of the conference to appropriate levels of government.

The idea was discussed further at the Coast to Coast Conference in Melbourne in 2006 and it was agreed that Bruce Thom develop a constitution of a company limited by guarantee that would operate on a national basis.

This plan was accomplished and in 2008 at the Coast to Coast Conference in Darwin the constitution was ratified and an Executive appointed. The company received charitable status in 2011.
