Seashore Engineering were engaged by the Department of Transport in June 2016 to refine the redevelopment concepts for Casuarina Boat Harbour with considerationof a harbour layout to balance flushing, sheltering and potential costs of the proposed breakwater.
Seashore Engineering completed an assessment of wave penetration for the proposed Casuarina Boat Harbour in Bunbury including the design optimisation of the proposed breakwater structures. This included an initial modelling of wave propagation within Koombana Bay using SWAN and an assessment of diffraction into the proposed harbour.
Subsequent studies used DHI MIKE 21 BW Boussinesq wave model to demonstrate the sheltering capacity of the proposed harbour layout and to determine the susceptibility of the harbour layout to long wave resonance.
