Suspended sediment dynamics in reservoirs and useful life of dams
We have studied the sediment trapping efficiency of the Burdekin Falls Dam, over several wet seasons, to examine siltation within the dam reservoir and to construct detailed ‘bulk’ suspended sediment export budgets for the Burdekin River. These data have been used to model sediment trapping for other reservoirs in the Great Barrier Reef catchments, to develop scenarios for future dam construction, and to predict the useful life of a reservoir. We have also examined the dynamics of sediment transport within the Burdekin Falls Dam to understand sediment transport, deposition and partitioning processes within the reservoir.
