Waterways draining into Moreton Bay are heavily used and in places are in poor condition. There are 24,000 km of degraded rivers that, in times of heavy rain, send sediment and pollutants into the Bay, damaging its environmental health.
eWater scientists from Griffith University in Queensland have estimated sediment load for the whole catchment could be effectively halved by rehabilitating just three of the major gullies.The scientists have brought together a suite of tools to trace a river’s sediments back to its source. The tools tell them whether the sediment originated as channel and gully erosion, or as shallow sheet or rill erosion further up hillslopes. In this way, the tools allow the primary sources to be identified and enable rehabilitation works to be targeted at those areas generating the most sediment. Read the article at this link following.
