techniques. In response, this project was commissioned to investigate the potential of reducing nutrients in irrigation drainage systems using in-line wetland technology and batter stabilisation.

Australian river systems are threatened by the severe effects of drought, bank erosion, sedimentation, pollutant inputs, urban development, and invasions by exotic aquatic plant species.

Submerged water plants (aquatic macrophytes) are a desirable component of shallow lakes and wetlands, and management activities should be directed to ensure their continual presence.
