Abstract
Abstract. Coastal vulnerability Index (CVI), is one of the predictive approaches to coastal classification by incorporating various coastal variables. This approach is favoured in the coastal investigation as it simplifies a number of complex parameters. However, it comes greatly as to why such assessment is developed in the first place; a) to facilitate coastal management in recent coastal condition, b) to classify potential shoreline responses to future sea-level rise, and c) for management of data storage. Index development in coastal investigation is one of the present-day technique used to estimate the vulnerability of the coast and is affected by a diverse range of variables. The widespread use of contemporary technology nowadays has led to a favourable coastal component to be considered in determining coastal vulnerability and environmental risk analysis. Therefore, it must be guided by acknowledging appropriate data to be used at spatial scale of interest, the geomorphology of the area concerns and etc. USA and European countries like Northern Ireland are one of the forefront country in addressing the significance of CVI in protecting coastal area. A stepwise approach to development of CVI is discussed in detail in this paper. Besides, the potential of including coastal components based on special characteristic at particular coasts for coastal vulnerability analysis are also reviewed. CVI eventually will assist coastal communities in providing guidance for mitigation of coastal threats in future urban development.
Highlights
Sustaining coastal processes, which characterized by important ecological and natural value, are essential since they provide ecosystem service that is deemed important for human wellbeing (MEA, 2005; Ramieri et al, 2011)
Coastal vulnerability is precipitated from the variability of physical, ecological and human characteristics prompted an effort to classify coasts using multidisciplinary information (LOICZ, 1995; Cooper and McLauglin, 1998)
A greater level of detail is required at the local scale in order to distinguish between areas of potential vulnerability. These results show that the scale of study determine different outcome at different scale; in which the area can be regarded vulnerable at one scale, but not at another
Summary
Sustaining coastal processes, which characterized by important ecological and natural value, are essential since they provide ecosystem service that is deemed important for human wellbeing (MEA, 2005; Ramieri et al, 2011). According to McLaughlin and Cooper (2010), the three elements of physical coastal characteristics, wave forcing and socio-economic characteristics contribute to overall vulnerability These multidisciplinary variables, represented by diverse type of data literally complex in assembling for coastal.

Each variable was assigned a relative risk value based on the potential magnitude of its contribution to physical changes on the coast as sea-level rises
