PORT OF NEWCASTLE, NSW, AUSTRALIA – MAINTENANCE DREDGING AND UNCONFINED SEA DISPOSAL OF DREDGE MATERIAL

Abstract

The Port of Newcastle is the largest port on the East Coast of Australia and the world’s largest coal export port. The port is located on the Hunter River, a major river in NSW having a catchment area of approximately 37,000km2 and a length of approximately 460km. The river is subject to freshwater flows and major flooding which introduce fluvial sediments to the port. Marine sediments are also introduced into the port entrance area by coastal processes. Continual maintenance dredging is required within the port to ensure safe navigation. It is fundamental to the continued operation and viability of the port.
