Impacts of Urban Floods on Road Connectivity - A Review and Systematic Bibliometric Analysis

Urban floods are paralyzing surface transportation and inflicting heavy economic losses. Climate-induced increase in frequency intensity of rainfalls excessive urbanization makes urban centers even more vulnerable to floods. It is necessary quantify all dimensions losses caused road connectivity improve flood mitigation policy. There a need consolidate the existing body peer-reviewed contemporary literature on inundation modeling its impacts connectivity. This will awareness policymakers researchers help science-based decision making. Articles archived Web Science database having keywords their title published between 1977 2020 were analyzed using blibliometrix library R. Analysis shows that extent has evolved from conventional hydrological models near real-time crowd-sourced methods. Applications geographical information systems advanced remote sensing methods have been growing identifying network vulnerabilities. We observed gap harmonized data availability, due unstructured formats at several scales, which hinders generalized approach for risk studies planning. Concentrated efforts be made fill gaps availability research methodologies, especially data. Further, awareness, early warning systems, alternate transport networks, make cities less
