Assessment of flood vulnerability of road infrastructure :

Abstract

Although the world has recently seen many disasters, flood impacts have garnered the most interest and attention due to their detrimental repercussions. Asia accounts for more than half of the world's flood losses and damages, which cause fatalities, infrastructure destruction, and public panic. The primary objective of the flood vulnerability assessment is to give people more knowledge about how to deal with flood dangers. In this case, vulnerability is the key idea in the study and evaluation of floods. Many scholars have specified different approaches and methods to comprehend vulnerability assessment and how geographic information systems estimate the susceptibility of flooding as well as the danger associated with it. Geographic information systems track, predict, and mitigate the effects of disasters. This study carefully evaluates the methods used to estimate floods and their dangers by integrating a geographic information system. We looked at papers on flood vulnerability from 2010 to 2020. Through the systematic review methodology of five research engines, the researchers were able to identify a gap in flood vulnerability assessment tools and methods that can be remedied by fusing high-resolution data with a multidimensional vulnerability methodology. The study reviewed a number of risk variables and focused on the weaknesses in key categories of flood susceptibility. According to the research, the indicator-based approach offers a better understanding of vulnerability assessment. To decrease the flood catastrophe, the geographic information system provides a suitable environment for precise analysis and mapping.
