Change in bar dynamics is caused by various aspects: degradation, armoring, vegetation etc. Though they multiply influence the actual bar dynamics, each role should be clarified separately. Ths paper focus on the role of the bed-material composition on the bar formation, particularly on the mechanism to determine the number of mode. We employ the numerical method specially prepared to describe the change of mode number in bar-development process and linear instability analysis for a bed with graded materials, and clarify how the mode number changes with the bed-materials composition.}, pages = {1003--1008}, title = {卓越砂州モード数へ及ぼす河床の粒度構成の影響}, volume = {48}, year = {2004} }
