Floodplains such as those in the northern Territory’s Kakadu National Park are likely to remain flooded for many months, meaning barramundi and crocodiles could move to remote parts of rivers where they're not usually found.

"The monsoon seasons of northern Australia have a huge effect on what animals and plants live where and when," says TRaCK researcher, Dr Neil Pettit from the University of Western Australia.  "They are also important for how a river functions."

A Tropical Rivers and Coastal Knowledge (TRaCK) research team has spent the past three years finding out more about how the Top End's rivers naturally flow, and what drives the healthy ecology and functioning of these rivers.  This will help river managers make more informed decisions about how these rivers are used in the future.
