초록
This study was conducted to analyze the development of valley floor and sand-gravel bar of Naechon stream, which is a tributary of upper Hong-Cheon river. The results of this study showed considerable changes in the direction and valley floor width of Naechon stream. The diversity of rocks determined the shape and characteristics of sand-gravel bar in the sections of Naechon stream’s valley floor. Even for small sub-basins, which are part of the upper stream basins, we recognized that their stream geomorphology must be studied by considering the development of rock distribution, shape of the valley floors and sand-gravels bar within the basin. This study which focuses on small basins in Korea is expected to provide basic data for comparative studies on many small basins in this area.
