Assessing the Potential for Algal Blooms in Clear Water Phase Tropical Rivers

Associate Professor George Ganff, from the University of Adelaide studied the rivers of northern Australia and particularly those in the Top End of the Northern Territory which are subject to major seasonal changes in flow and inter-annual variability. During the dry season, spring water maintains flow with different water chemistry from the rainfall run-off that constitutes wet season flow.

Water regime dependence of fish in the wet-dry tropics

This project has improved understanding of the potential ecological impacts of changes in dry season flow regimes of tropical river ecosystems caused by water resources development in these catchments. The project investigated variation in fish distribution and ecological requirements across a natural flow regime gradient using field sites, and document indigenous knowledge on fish in the Daly River. This information has been used to develop models, based on BBNs, to predict the impact of different (more)...
