"Often during flood events, water from agricultural catchments will erode productive agricultural soils and carry large loads of sediment and nutrients to downstream estuaries and coastal areas. This can threaten the provision of safe drinking water for humans and the ecology of marine ecosystems, as well as sometimes necessitating costly sediment dredging and disposal operations."
"Revegetating abandoned agricultural land is critical for maintaining sustainability and biodiversity within our farming landscapes. Our recent paper demonstrated the feasibility of a large-scale revegetation approach in one of Australia’s most iconic agricultural regions, the Murray-Darling Basin."
Author's Dr Songyan Yu and Associate Professor Mark Kennard, Read Time: 622 words, about 3 minutes. There is a growing interest globally in the spatial distribution and temporal dynamics of intermittently flowing streams and rivers. Previous studies have predominantly relied on the use of gauged streamflow data to make inferences about the distribution of intermittent streams. [...]

Rivers, lakes, and wetlands support extraordinary diversity. Such bodies of water host more species per square kilometre than forests or oceans. Yet they are losing this biodiversity two to three times faster than forests and oceans. Populations of freshwater animals, including river dolphins, sturgeon, beavers, crocodiles, and giant turtles, have already plummeted by 88%.

The 2019 Great Barrier Reef Outlook Report from the Australian Government Great Barrier Reef Marine Park Authority identifies the risk of nutrient runoff from catchments for the reef as Very High, the same rating as the 2014 and 2009 reports. --- This [...]
By Dr Chris Brown Reading Time: 557 words about 3 minutes. We usually think of nutrients moving down rivers to the ocean, not the other way around. But in many temperate rivers of the northern hemisphere migration of salmon brings nutrients from the ocean to rivers and surrounding vegetation. Male Pink Salmon, identifiable because of [...]
Australian Rivers Institute Director, Stuart Bunn. We welcome you back to another edition of the Australian RiversInstitute (ARI) Magazine. (Link). Over the past few months our staff have been active in strengthening research partnerships and establishing new connections across the globe. The importance of connections, not only with fellow researchers, industry and government but also [...]
By Professor Michele Burford Reading Time: 537 words, about 3 minutes. Algal blooms are a major issue for water security globally and in Australia. We have seen the damage algal blooms have had on Murray-Darling Basin and the issues Florida have had with the recent 'red tide' epidemic. As our climate changes, we can expect [...]
