Integrated Methodology for Assessing Vulnerabilities of Infrastructure for Extreme Climate Events

The infrastructure vulnerability to the climate change is increasing around the world and its implications are evident in many sectors. Settlement patterns, urbanization, and changes in socioeconomic conditions have all influenced observed trends in exposure and vulnerability to climate extremes. Small island states are particularly vulnerable to climate extremes, especially where urban centers and/or island infrastructure predominate in coastal locations. Asia’s mega-deltas are also exposed to extreme events such as storm surge flood and have vulnerable populations in expanding urban areas. This research is focused on developing an integrated methodology to identify infrastructure vulnerability exposed to tropical cyclone along the sea coastal. Infrastructure is commonly defined as the various components of the built environment that support modern society (e.g., Choguill 1996). These encompass utilities, transportation systems, communication networks, water systems, and other elements that include some of the most critical underpinnings of civilization. Thus even modest disruptions to infrastructure can have significant effects on daily life, and any systematic change in the frequency or intensity of those disruptions could have profound consequences for economic and human well-being.

The general concept of vulnerability can be analysed in three main categories: physical, systemic and organizational/social vulnerability. In this study we are focused only on the physical vulnerability: investigates how much items like population, residential buildings, critical facilities, industries and lifelines are prone to a dangerous phenomenon. Even though the other two categories are not considered in this work, they are also very crucial to define the risk, and then the expected damage associated at the hazard. Using the dimension proposed by Fussel (2007) the vulnerable situation can be defined as: “vulnerability of a system’s attributes of concern to a hazard in temporal reference”.
