Parallel session: Poster pitches: 9I. Extreme - Flood Drought
Cities are becoming increasingly vulnerable to flooding because of rapid urbanization, installation of complex infrastructure, and changes in the precipitation patterns caused by anthropogenic climate change (Willems, P. et al., 2012) Korea is also concerned about dangerous and fast progressing climate change that influences the quantity and quality of water resources (Park. H.S. et al., 2014). Accordingly, it is necessary to predict the future precipitation using the climate change scenarios provided by Korea meteorological administration (KMA). The applicability of evaluation is required prior to using the climate change scenarios. In this study, we evaluated the applicability of the daily precipitation from the RCP scenarios provided by KMA and improved the problem in order to solve the water issues. Particularly, we evaluated by comparing the spatial composition of climate change scenarios grid map and the current topography. There was a lack of more than 4,000 grids (1km_1km) around the coastal area. So we created new grids for these area using the Arc-GIS. The resulting map from our study is covering now the entire area of the South Korean Peninsula so it can be used for future water resource assessments.
