Nutrients in rivers

A common result of human activity in catchments is an increase in the amount of sediment and nutrients (phosphorus and nitrogen) found in rivers.  This project answered questions about how changes to the sediments and nutrients found in rivers affect the processes and plant growth in rivers.

The project was led by Dr Barbara Robson from CSIRO Land and Water in Canberra. Other researchers in the team came from a broad range of agencies and institutions including CSIRO Marine & Atmospheric Research (Hobart), Griffith University (Queensland), Charles Darwin University (Darwin), Geosciences Australia (Canberra) and the NT government.
