Coastal Modelling and Management

Natural forces of winds, waves and currents constantly shape our coastline, resulting in an everchanging seascape.

Coastal beaches continually erode and accrete, with most beaches achieving a dynamic equilibrium through a balance in supply and loss. However in some locations where sediment supply is interrupted, foreshores can continue to recede. Human activities can have a major impact on coastal processes. Our challenge is to meet the increasing pressure to develop the coastal zone with environmentally sound practices - ensuring that coastal amenity and natural character are protected.

BMT WBM highly respected team of professional coastal engineers and scientists regularly investigate all facets of the physical and ecological coastal system.  We have a wealth of experience in preparation of plans and strategies for coastal management and we are leading the way in providing expert consultancy services to local governments and decision-makers under new coastal legislation around the country.

Coastal studies regularly undertaken include:

  • Baseline data collection studies
  • Investigations of coastal processes and erosion problems
  • Advanced computer modelling (1, 2 and 3D) of waves, currents, water levels and  sediment transport
  • Hydraulic and sedimentation studies of estuaries, ports and marine projects
  • Port planning impact assessment studies
  • Dredging and dredge material management strategies
  • Sand bypassing investigations
  • Coastline hazard definition studies
  • Coastal management planning
  • Coastal lake entrance management
  • Metocean modelling and data collection.
  • Estuary and Coastal Zone Management and Planning

    For more than 20 years, BMT WBM has undertaken projects of this nature along the entire East Australian coastline. We have a long and proven track record in helping clients to understand and manage these challenges of the coastal zone.

  • Coastal and Offshore Modelling

    BMT WBM utilises a range of state-of-the-art modelling software to simulate these processes, including detailed two and three dimensional flexible mesh systems developed in-house (TUFLOW-FV).

  • Sedimentation and Dredging

    This may involve sand that moves along the coast and nearshore areas or fine cohesive mud material suspended in bays and estuaries by waves and currents.

  • Coastal Structures

    This may involve assessment of the most effective fit for purpose structure layout while minimising or mitigating its impacts on the adjacent coastal environment.
