Geomorphological Understanding for Improved Island Management at Raine Island: Cay Evolution, Morphodynamics and Sediment Budget (Old ID 23009)

BHP Billiton Group Operation Pty Ltd
Role

Principal Investigator

Description

Raine Island is a cay composed of sediments produced on the surrounding reef. Its geomorphology is highly sensitive to changes in reef community composition and productivity that affect sediment production and delivery to the day, and depositional and post-depositional processes that affect net cay volume. A complete and accurate sediment budget is fundamental to understanding cay morphodynamics, for modelling geomorphic trajectories, and to address key management issues associated with such changes. This research will significantly improve the existing sediment budget for Raine (constructed using data from other reefs) by using productivity, transport, deposition and sediment attrition data collected on site.
