| Two dimensional finite element model(RMA) is applied to examine sediment transport behavior near Buyeo water intake station of the Keum River. The simulation results of bed change with various discharge conditions agree with those of observation. As the alternatives of channel modification and resulting bed lowering near intake station, construction of jetties and removal of small island are considered. The station of jetties diverted the main stream toward the other side and the width of the main stream did not change so much. The bed elevation of the main channel is reduced about 5~20 cm, when flow condition of 12,030§©/sec applied. The removal of small island provides the less significant effect on sediment movement. This study shows that the construction of jetties would be effective to reduce the entrainment of sediment. |
