Coastal hazards advisory

Assessing the risks to a coastline posed by hazards such as erosion and inundation is an essential first step for any proactive coastal authority looking to identify the long-term impacts of ongoing coastal processes, increasing pressure from development and amenity access, together with climate change impacts.

Coastal communities and infrastructure have always faced the risk of erosion and storm tide flooding. Still, climate change has raised the stakes, making it more critical than ever before to be prepared for and protect your resources from damage.

We identify, gather, and review critical information to support more innovative planning and investment decision-making concerning coastal hazards and use our state of the art modelling solutions to assess the extent and timing of impacts.

Once the hazard risk is better defined, we help you prepare appropriate responses to coastal hazards and climate change across planning, engineering, financial and operational responses.

Our experience includes:

  • Shoreline erosion and tidal inundation mapping studies including future conditions such as sea-level rise and increased storminess
  • Coastal management options studies include reviewing cost comparison and benchmarking of different coastal management solutions.
  • Operational coastal management solutions such as complex engineering works, soft engineering works such as beach nourishment and developing passive dewatering systems for reducing beach erosion.

Coastal Hazard Risk Management and
Adaptation Planning (CHRMAP)

We have carried out several studies
where we work closely with stakeholders to apply their risk profile and prioritise the required management and adaptation actions throughout the planning timeframe. In addition, we design adaptation measures to establish a site-specific coastal management tool, enabling clients to make informed and timely decisions.

Ultimately, this process allows the
development of risk profiles for the coast
and identification of the potential impacts
of climate change and associated rises in
mean sea level.

Coastal hazard and
vulnerability assessment (CHVA)

Establishing the physical characteristics
of the coastal area through reviewing the
coastal processes and geomorphology is
fundamental to providing a platform of
understanding, and can include the
following potential components of coastal

  • Short-term storm-induced erosion
  • Historical shoreline recession
  • Recession due to sea-level rise
  • Coastal inundation

Availability and high quality of data,
including nearshore wave climate and
bathymetry are fundamental to the
development of meaningful outputs from
