Dr Scott Wilkinson

Scott Wilkinson researches the sources, transport processes and management of river basin sediment and nutrient loads. His research approaches include spatial process modelling, sediment source tracing, field monitoring, and targeting and designing erosion rehabilitation activities.

Recent research topics:
* Modelling the sediment and nutrient exports to freshwater and coastal environments, including the Great Barrier Reef Lagoon, Westernport Bay and water supply reservoirs
* Defining the sediment yield of gully erosion in tropical rangelands draining to the Great Barrier Reef
* Prioritising and evaluating gully rehabilitation techniques.

Dr Wilkinson provides technical advice on implementing cost-effective gully and stream bank erosion control, and on evaluating the resultant reductions in sediment delivery to the Great Barrier Reef lagoon. He designed the catchment sediment budget framework used to report the outcomes of water quality improvement programs in the Great Barrier Reef catchment area. He contributed to the Great Barrier Reef Water Quality Scientific Consensus Statements in 2008, 2013 and 2017 and chaired the 8th International Symposium on Gully Erosion in 2019. Research collaborators include several universities and government agencies.
