The scientist helping Australia and India tackle common water quality challenges
CSIRO environmental toxicologist Dr Anu Kumar is leading a project tracking pollutants in the Ganges.

Researchers trust their tools when it comes to looking after the Great Barrier Reef
Deteriorating water quality is one of the biggest threats to the Great Barrier Reef. Vital protection and recovery efforts are taking place in the catchments adjoining this national treasure's coastline.

Waterbirds in northern Australia: birds of a feather, grouped together
Northern Australia is home to a diverse and unique range of waterbirds. Scientists have created four functional groups of waterbirds, helping decision makers better understand the potential impacts of water and agricultural development in the north.

Can we have healthy marine ecosystems and modify rivers in northern Australia?
We’ve used a novel ecosystem modelling approach to demonstrate how river flows are the lifeblood of marine ecosystems in the Gulf of Carpentaria.

Uncertainty: The X factor behind more reliable streamflow forecasts
A new national forecasting service is giving dam operators, river managers – even kayakers – a clearer picture of river and stream flows up to a week in advance. Paradoxically, uncertainty is a key to more reliable forecasts.

The challenge at the end of Australia’s mighty Murray-Darling system
Management of the Lower Lakes system in South Australia has been informed by extensive science. Understanding the impacts of climate change and adaptation remain future challenges for the region and the Murray-Darling Basin as a whole.

Understanding complex interactions the key to the freshwater croc’s future
A failure to grasp the details of the life of freshwater crocodiles in the places they live is likely to bedevil their conservation.

Understanding water pressures
With many surface water storages, such as reservoirs, empty or critically low, groundwater (underground aquifers fed by rainfall and found in cracks or pores in rock) supplies are critical for many Australian communities and industries.

Understanding ecosystem response to water management in the Murray-Darling Basin
While knowledge of water availability is key to managing Murray-Darling Basin water resources, a commensurate understanding of ecosystem ecological response to flow regulation is also required to aid environmental management.
