 note = {急流な礫床河川では，流路変動に伴う側方侵食によって堤防決壊などの深刻な被害が生じることがある．そのため，低水護岸等の設置によって河道拡幅を抑制する対策が必要となることもある．しかしながら，河道拡幅の抑制が河道内の流路特性にどのような影響を与えるのか未だ明らかでない点も多い．本研究では，護岸等の固定壁で河道拡幅を抑制する場合に側岸からの土砂の供給が遮断される影響に着目した検討を行った．移動床実験において，側岸からの土砂供給が無い場合，側岸沿いに洗掘域が延伸する過程とともに流路の分岐箇所が減少することが示された．また，上流側からの供給土砂量の大小が側岸沿いに洗掘域が延伸する影響を低減または助長することを示した．, In the gravel bed river, serious damage of such as levee failure may be caused by lateral bank erosion with the channel change. Therefore measures to control the channel widening are often carried out by setting such as the low-water channel revetment. However, some influence of channel widening restriction on the characteristics of channel plane is not clear yet. In this study, we examined focusing on the influence that the sediment supply is insulated from the bank when restraining channel widening by the fixed wall. Our movable bed experiments showed the process of increases in the watercourse wavelength along the bank by the influence which has no sediment supply from the bank, and the possibility that the quantity of sediment supply from the upper reaches reduce or promote that influence.},
