| In this paper, impervious area ratios for 11 land cover types of Seoul city were estimated and corresponding CNs were calculated. And linear regression equations were derived to predict impervious area ratios based on five major urban land cover types including the residential, industrial, transportation, commercial, and commercial-residential mixed areas. From the comparative analysis of impervious area ratios for the US SCS CNs and the CNs derived in this study for Seoul city, it is revealed that residential areas show the biggest difference followed by industrial and commercial ones. And in turn, these increased impervious area ratios resulted in Increased CNs for Seoul city including increases by 13 for residential, 12 for industrial and 5 for commercial areas. Therefore, it is suggested that applying the US SCS CNs to Korean urbanized areas may underestimate the flood runoff potential. |
