“…Since three decades several works have been made to establish strategies and procedures for evaluating coastal vulnerability to climate change and other related aspects, accompanied with economics (Cutter et al 2003;Lewsey et al 2004;Vincent 2004;Rygel et al 2006;Phillips and Jones 2006;Hinkel et al 2009;Torresan et al 2012;Addo 2013;Tang et al 2013;Wolters and Kuenzer 2015;Denner et al 2015;Wu et al 2016). A summary of several methodologies established and applied globally is provided here.…”

“…The CVI outcomes can be shown on vulnerability maps at various scales to identify regions where the elements that add to coastal changes make greatest contributions to coastline retreat (Harvey and Woodroffe 2008;Pendleton et al 2010). First coastal vulnerability index was developed by Gornitz (1990) followed by several researchers developing diverse CVI indices across the globe (McLaughlin and Cooper 2010;Palmer et al 2011;Yin et al 2012;Denner et al 2015). …”

Coastal infrastructure vulnerability: an integrated assessment model

The significance of coastal regions to the infrastructure and the need to protect such assets are crucial to the economy of countries. Therefore, there is a real need to enhance the understanding of coastal infrastructure susceptibility as well as to develop methodologies to estimate vulnerability. A review of the literature regarding coastal vulnerability reveals that the focus has been on geomorphological and physical parameters but not infrastructure and the associated fiscal factors. In order to address this knowledge gap, an innovative model is developed, i.e., the Coastal Infrastructure Vulnerability Index (CIVI). Then the model is applied to the case of the Aberystwyth coast demonstrating how the model estimates the vulnerability of the coastal infrastructure (comprising population, commercial and residential properties). Subsequently, the CIVI scores were used to rank coastal sections into five classes, ranging from extremely low to extremely high, based on the relative magnitude of the vulnerability. The rankings for each parameter were combined, and then an index value was calculated. Results revealed that Aberystwyth contains more than £40 billion of coastal infrastructure vulnerability and more than 10,000 inhabitants are at the high coastal risk posed by flooding, erosion, storm surges, and strong winds.

“…There is little variation in mean wind speeds and wind gust speeds around England (Met Office 2016) and, therefore, storm climate was not considered. The main parameters for assessing the vulnerability of coasts to erosion are the coastal geomorphological type, coastal slope, sediment balance, beach width, and vegetated areas (McLaughlin and Cooper 2010;Rosendahl Appelquist 2013;Denner et al 2015), and landfill assessments also consider the presence or absence of flood defences and the distance from the landfill to mean high water (Alaska Department of Environmental Conservation 2015). Here, features of the landfills were considered in place of the natural geomorphology and underlying geology.…”

“…Here, a five-point severity scale for each parameter is used with the highest values indicating the greatest hazards or vulnerabilities of receptors (Table 1) (e.g., Palmer et al 2011;Gill et al 2014;Denner et al 2015). Wherever possible severity scores from existing risk assessment methods have been utilised, but new severity scoring systems are proposed where necessary.…”

Risk screening assessment for ranking historic coastal landfills by pollution risk

Globally there are significant numbers of historic landfills, and in England alone there are over 1200 in low-lying coastal areas. Approximately one-third of these historic coastal landfills are near designated ecological sites, and without intervention, 10% are expected to start eroding within 40 years. Indeed, some sites are already eroding and releasing waste, and erosion is likely to become more common with the anticipated effects of climate change. Mitigating the pollution risk from all historic coastal landfills under threat of erosion would be prohibitively expensive; consequently, it is necessary to understand which sites pose the greatest pollution risk to prioritise management resources. This paper proposes a new risk screening assessment that can support coastal managers in identifying which historic coastal landfills pose the greatest pollution risk at a national scale for minimal cost using existing datasets. The proposed method determines an overall risk index for each site by considering the risk of pollution from eroding historic coastal landfills in two stages: the first stage assesses the risk of waste being released (waste release index), and the second assesses the risk to various receptors (pollution index). The highest risk sites can then be prioritised for further investigation or remediation.

“…Some coastal regions around the world have been categorised and evaluated using various coastal vulnerability indices [27], which have been developed in recent decades by incorporating various physical, geomorphological, socio-economic, and geological parameters within a myriad of formulations [28][29][30][31][32][33][34][35][36][37][38][39][40]. Vulnerability assessments have now become commonplace in the fields of physical and economic geography, environmental science, and other related research areas, such as climate change, sustainability, and ecology [41].…”

Climate change and associated factors such as global and regional sea-level rise; the upsurge in high-intensity flooding events; and coastal erosion are pulse and press disturbances that threaten to increase landslides in coastal regions. Under these circumstances; a rigorous framework is required to evaluate coastal vulnerability in order to plan for future climate change scenarios. A vast majority of coastal vulnerability assessments across the globe are evaluated at the macro level (city scale) but not at the micro level (small town scale); particularly in the United Kingdom (UK). In order to fill this vital research gap; the current study established a coastal vulnerability index termed here as the Micro Town Coastal Vulnerability Index (MTCVI) and then applied it to Barton-on-Sea; which is a small coastal town of the Hampshire region; England; UK. MTCVI was evaluated for Barton-on-Sea coastal vulnerability by integrating both novel and existing parameters. Results suggest that the entire shoreline frontage (2 km) exhibits very high coastal vulnerability and is prone to various coastal hazards such as landslides; erosion; and wave intrusion. This suggests that Barton-on-Sea coastal amenities will require a substantial improvement in shoreline protection measures. In this study; GIS (geographic information system) coastal vulnerability and landslide maps were generated; and these maps can be used by the local authorities; district councils; coastal engineers; and planners to improve and design coastal management strategies under the climate change scenarios. Meanwhile; the methodology used in this study could also be applied to any other suitable location in the world depending on the availability of the data.
