The effects of climate change are far reaching. One such effect has been flood damage. In particular urban areas are one of the most vulnurable places to increasing flood disasters. This is in large part due to the chararctertistics of urban areas: they feature a high rate of impervious area, urban development is constructed in vulnurable areas and they hold a high concentration of people along with vital infrastructure. The Korean government has prepared various disaster prevention measures, such as traditional disaster that are effected by climate change. In order to effectively decrease flood damage in urban areas, it is vital that the government improve disaster prevention measures. Simultaneously, they must also address the disater prevention system including various acts, planning, organization, work and budget, and how they will respond to the future impacts of climate change.
In this research, the Urban Flood Prevention System diagnoses to prepare with the effects of climate change. Based on the result of this diagnosis, subsequent improvement measures have been proposed. The SPR (Source-Pathway-Receptor) model is used to diagnose problems and propose improvement measures for the urban flood prevention system. The SPR Model is also used to analyze the link between the national land plan, the disaster prevention plan, the disaster prevention projects and risk management. In the SPR Model, S (Source) means meteorological factors which cause floods such as heavy rainfall; P (Pathway) is the path of potential floods; and R (Receptor) is the target which receives the damage directly, such as people, infrastructure and so on. The first step to diagnose the urban flood prevention system is to classify the various urban flood prevention measures within SPR. The flood forecast warning system and evacuation system are classified to the S sector, and the designation and management of the flood hazard area and space plan are classified to the P sector. For urban flood prevention measures, the urban flood measures are set to the R sector. Based on the urban flood prevention measures classified by SPR, the main problem of urban flood prevention system has been successfully diagnosed. The diagnosis takes into account the main causes for urban flood disasters by using recent urban flood cases as well as information from the changing direction of urban disaster prevention system, which has been proposed by other international organizations and agreements. From the perspective of reinforcement, connectivity and effectiveness, problems of the disaster prevention system by SPR are identified. Also, the detailed diagnosis aspects by SPR are established. Using the modified SPR model, the main problems of the urban flood prevention system preparing to climate change effects are diagnosed.
Based on the diagnosis of the urban flood prevention system and policy implications from the U.S., Japan, and the U.K., the goals and main improvement measures for each SPR of the urban flood prevention system are proposed. First, the main goal of the S-sector is a quick and safe evacuation. The improvement measures for S-sector are the systematization of applicable provisions for the flood forecast warning, simplification of flood warning signs, reinforcement of the flood forecast warning system, reinforcement of connectivity and cooperation of the flood forecast warning system and reinforcement of connectivity between the flood forecast warning system and reinforcement of connectivity between the flood forecast warning system and evacuation. For the P-sector, the main goal is the proactive designation and management of flooding hazard areas. The main improvement measures include the decrease of the redundancy of flood hazard sorts, actualization of applicable provisions for flood hazard area selection and the development of the integrated guideline between the natural disaster prevention plan and urban plan. Finally, the main goal of the R-sector is the reinforcement of the connectivity and effectiveness of work. In order to achieve the R-sector’s main goal, improvement measures including the conversion from temporary opeartion to regular operation of the Central Division of the Natural Disaster Prevention, reinforcement of disaster prevention teams in regional governments, and invigoration of the disaster relief funds have been proposed. The proposed improvement measures for the urban flood prevention system would be helpful to reduce the effect that climate change has on urban floods.
