Gully symposium brings erosion ‘brains trust’ to Southern Hemisphere for first time

Erosion from gullies is a major source of sediment impact on the Great Barrier Reef lagoon. Mitigating this erosion is therefore key to improving water quality in Australia’s tropical marine ecosystems. In late July the world’s experts on gully erosion, including two research teams from the NESP Tropical Water Quality Hub, met in Townsville for the 8th International Gully Erosion Symposium, the first time the event had been held in the Southern Hemisphere. Both Associate Professor Andrew Brooks from Griffith University, whose NESP TWQ project improves our capacity to map and monitor gully erosion, and Dr Rebecca Bartley from CSIRO, whose NESP TWQ project evaluates the effectiveness of gully remediation efforts, delivered presentations at the Symposium. Dr Bartley spoke about trialling different erosion mitigation techniques and said it was an excellent opportunity to access the global ‘brains trust’ on erosion. “It was great meeting and a key highlight was being able to talk to people from other parts of the world that have a lot of experience working on remediating gullies,” she said. “They’ve provided some great insight and advice on gully erosion in the Great Barrier Reef context.”Dr Bartley’s presentation and Assoc Prof Brooks’ presentation at the Gully Symposium are both available on the TWQ Hub website.
