Abstract
In this study, proposes a method of risk assessment so that local governments can minimize damages of road flooding caused by natural disasters(heavy rain, typhoon) and to establish systematic disaster prevention measures. To this end, the risk assessment of road flooding consists of four main factors. These factors are evaluated in terms of disaster indicators for probability, consequentiality, vulnerability, and reducibility, respectively. The evaluation criteria for hazard and exposure were prepared by analyzing the occurrences and damages of road flooding in the last 24 years by local governments. And, based on available statistical data for each local government, demographic, social, and facility indicators are selected for vulnerability factors, and medical, policy and administrative indicators that are reduction factors are selected. The risk assessment of road flooding for local governments was derived through the evaluation results of each risk assessment factor. The results of the risk assessment by road flooding conducted in this study will be able to contribute to establish the efficient and systematic road flooding prevention measures for local governments.
