Coastal erosion and the sediment budget, with special reference to the gold coast, Australia

摘要: Abstract Coastal erosion management demands knowledge of the sediment budget problem area. The Gold Coast is unusual in that it longshore transport dominated but receives little or no sand from freshly weathered rock; palimpsest and derived Pleistocene beach ridge systems well updrift. Moreover, both Holocene sinks are either subaerial shallow subaqueous; submarine canyons exist region. Some evidence exists for two inner shelf sinks. Supply updrift stores has until recently buffered impact late erosion, there likelihood natural increases supply future.
