Abstract
The prediction of fine cohesive sediment erosion is important information for civil engineers. However, to calculate an actual amount of erosion, the necessity for considering the effect by biofilm formed on the bed mud surface has been caused. Biofilm formed on the bed mud has a major influence on the erosion phenomenon in estuaries. Therefore, many researchers are grappling from various angles with this problem.Experiments were carried out in an annular flume at the Water and Environmental System Laboratory of Fukuoka University. Results of an experimental study on the effect of biofilm for fine cohesive sediment erosion in the annular flume are described. The relation between biofilm on the bed mud and the initial rate of erosion were conducted under the condition to adjust the amount of light and water temperature. The thickness of biofilm reached about 2mm in the maximum and 0.5mm in the minimum. In this study, it has aimed to clarify how the amount of bed mud erosion changes by the biofilm experimentally
