• 要約等: <p> Open channel experiments were conducted to investigate influences of bed roughness conditions on the detachment of attached algae by sediment transport. The experimental results showed that sediment deposition was observed between gravels in a hemispherical gravel riverbed and that the presence of sediment deposition significantly affects the amount of detachment of algae. In the case that sediment is deposited, the detachment was not significant because there was a small area where the sediment acts to detach algae from the gravels. The detachment characteristic values, exponents to evaluate detachment rate, also decrease with an increase in dimensionless deposition height. By introducing a sedimentation coefficient, the effective amount of work was calculated considering the effect of sedimentation. This enables the estimation of the detachment characteristics of the hemispherical gravel beds.</p>
