    Cape Jaffa Marina Sand and Dredge Management Plan

    A sand and dredge management plan for the Cape Jaffa Anchorage on South Australia's Limestone Coast, built on wave and sediment transport modelling, that moves the marina from emergency dredging to a planned, trigger based maintenance program.

  • Semaphore SLSC

    Semaphore Surf Life Saving Club Coastal Adaptation

    Coastal erosion hazard assessment and adaptation concept design for the Semaphore Surf Life Saving Club watch tower on Semaphore Beach, South Australia.

    Sheringa Beach Access Stairs Replacement Design

    Storm damage assessment and replacement design for the public beach access stairs at Sheringa Beach on the western Eyre Peninsula, realigned onto more stable ground so the new structure can withstand the dune erosion and wave exposure of an open Southern Ocean coast.
