Hydrodynamic and Ecological Assessment of a Sub- Tropical Stream in Eastern Australia

A detailed multi-disciplinary field study was conducted in a small subtropical creek in Eastern Australia. Hydraulic and ecological measurements were conducted simultaneously in the river mouth to assess the complexity of a small estuarine system, and the interactions between hydraulic engineering, environmental issues, biology and ecology. The results provide an unique and original snapshot of a subtropical creek system and set new standards for comprehensive surveys of small estuaries in sub-tropical zone. A key feature of the results was the contrasted outcome. Fauna observations showed strong bird and fish activities. But, some aspects of the study demonstrated on-going pollution.
