What is a coastal vulnerability assessment and how do you complete one? Although intended to be a simple process, there is often confusion on how to undertake an assessment. Establishing the objectives, planning the methodology and defining the expected outcomes can all be difficult to comprehend.
A coastal vulnerability assessment moves the focus from coastal processes and understanding physical changes in the position of the shoreline, to identifying the impacts on assets within the coastal zone. Having a clear understanding of the relative vulnerability of assets provides the essential guidance on the need for, and prioritisation of, future planning and adaptation. Vulnerability is usually defined as the combination of exposure, sensitivity and adaptive capacity. This uses different terminology to a conventional risk assessment (likelihood and consequence). However, there is significant commonality between the two processes.
In this paper, we explore the synergies between a vulnerability assessment and a risk assessment and identify opportunities where they can be combined. In doing so we present a simple framework and methodology for undertaking a coastal vulnerability assessment. The method has been found to meet the requirements of the Western Australia State Planning Policy No. 2.6 State Coastal Planning Policy and be consistent with the Western Australian Coastal Hazard Risk Management & Adaptation Planning Guidelines.
