Abstract

The sand bar has developed at the junction of the Kum-ho River and Shin-ryoung River. The sediment transported from the Kumho River basin has decreased since the Youngchon Dam has been functioning. Sand bar and the vicinity of the bottleneck at the upstrem of Kumho River and Osu Island which is consisted of sand bar have inundated frequently. This study was carried out through the hydraulic model test to calibrate the hydraulic effect from removal of sand bar in the river and straightening the river course by land reclamation. The water level of river at the vicinity of bottleneck can be lowered as much as 0.40~0.7m when the sand bar is removed. When river is straightened the river course by land reclamation the water level can be lowered as half of removal of sand bar.
