A detailed sedimentation investigation at two open channel outlets at Bowen, Queensland. Marine sediment has been accumulating at two open drains, which required ongoing mechanical excavation. The assessment has considered a new approach to manage sand accumulation with a manually operated flush gate, which has been designed using a long-term sediment transport model and Beach Evolution Model, and Computational Fluid Dynamics (CFD) modelling of hydraulics and scour using Flow-3D.
