Abstract—Local governments in Korea are facing increasing calls to predict climate change impacts and prepare corresponding adaptation countermeasures. However, efforts to analyze climate change impacts are mostly at the macroscopic level due to limited data acquisition and an inability to analyze the climate change phenomenon. This study developed a grid-unit climate change impact assessment model in consideration to urban infrastructure to enable more specific impact analyses to be conducted and for the establishment of response measures.
The assessment methods consist of four parts: 1) Investigating the locations previously damaged by floods; 2) establishing a statistics-based analysis model to predict potential flood areas, 3) investigating the presence of infrastructure located within a flooded area; and 4) analyzing future climate change impacts.
Through the developed assessment model, more concrete climate change impacts on an urban infrastructure was identified at the level of 1km× 1 km resolution. In addition, it was found that minimizing the surface flow by maintaining sewage pipe lines and expanding green infrastructures were effective.
