Geomorphic and vegetative controls of streambank stability and channel migration in streams of tropical Queensland.

Streambank erosion and channel migration are natural processes, but major environmental and management problems can arise when they are accelerated by human activities. This project aims to establish how channel morphology and riparian vegetation characteristics influence streambank stability and channel dynamics for streams in tropical northeast Queensland. A predictive model of streambank and channel stability will be developed that will allow mobile and stable stream reaches to be identified. This model may be applied to optimise stream stabilisation and rehabilitation strategies, and to improve local riparian and downstream ecosystem quality.
