Abstract
The change of stream creation has a very sensitive effect on runoff analysis model using the divergence characteristic of stream. Therefore, in this study, the threshold area of stream creation was examined the change characteristic of topographical parameters. The subject basin of the research was the upper basin of the Kumho water gage station which is located in the middle of the Kumho river. The 1:25,000 numerical geography which was constructed
본 연구에서는 최소차하천의 임계값에 따른 지형매개변수의 변화특성을 분석하였다. 분석을 위하여 금호강 중류의 금호수위표지점 상류 유역을 대상으로 하였다. 분석에서는 유역내의 1:25,000 수치지형도를
