Abstract
The purpose of this study is to evaluate the hydrological impact due to temporal land cover change by gradual urbanization of Anseong-cheon Gongdo watershed (371.8 ㎢). Land covers of 1981, 1990, 2000 Landsat TM images were classified by maximum likelihood method. The watershed showed a trend that forest & paddy areas decreased about 33 ㎢ and 27 ㎢, respectively and urban area increased about 11 ㎢ during the periods. To identify the impact of streamflow due to urbanization, WMS HEC-1 was used. According to apply Huff's quartile storm events by changing land cover data, peak runoff discharge of each frequency rainfall (50, 100, 500 years) increased about 56, 36, 192 ㎥/sec, respectively.
