Climate change and urban flood damage in Korea

Abstract:

Due to the climate change and the rapid growth of urbanization, the frequency of concentrated heavy rainfall has increased causing urban flood. It has been increased in casualties and property damages due to urban flooding caused by hydrometeorlogical extremes according to climate change. As a consequence of natural disasters that occur annually, the number of casualties and cost of damage in Korea is to be over 2 billion US dollars per year. Therefore, in this study, we studied the climate change in Korea and developed an integrated flood analysis system that systematized technology to quantify flood risk and flood forecasting in urban areas for supporting synthetic decision-making through real-time monitoring and prediction on flash rain or short-term rainfall by using radar and satellite information.
