Gullies that start on the steep banks of rivers and cut into terraces or elevated floodplains (alluvial gullies) are a major factor affecting the water quality of the Great Barrier Reef.\u00a0Griffith University\u2019s Associate Professor Andrew Brooks is leading a NESP Tropical Water Quality Hub project<\/a><\/strong> to test the effectiveness of different techniques used for rehabilitating these large alluvial gullies.\u00a0Working with Cape York NRM, Greening Australia and the Queensland Government, they are trialing a variety of methods including earthworks, gypsum application, mulching, rock capping, and revegetation to reduce the sediment delivered from highly active gullies.\u00a0To see some of these techniques in action, this video<\/a><\/strong> of rehabilitation works on a major gully system at Crocodile Station in Cape York Peninsula, demonstrates that a 0.6-hectare gully system with a total erosion rate of around 260 tonnes per year has been effectively \u2018turned off\u2019 after two years at a cost of around $400 – $1,000 per tonne per year.\u00a0More information about this project is available online<\/strong>.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
