Rivers and Estuaries Science Program 

The Rivers and Estuaries Science Program undertakes and supports research across a wide range of disciplines to address knowledge gaps and inform management of the Swan Canning Riverpark.  

Research is aligned with the department’s Science Strategic Plan 2022-2025 and WA Marine Science Institute’s estuarine research priorities. Strong collaborative linkages exist with universities, research centres and other government departments. 

Scientific advice and support is provided to the Rivers and Estuaries Branch in relation to waterway condition, management, and incident response including algal blooms, fish-kills, sewage overflows and dolphin deaths.
