Abstract
Since local scouring occurring at the foot of a flow-sediment control structure impairs the stability of the structure itself, it is required to take some measures by predicting the scale of the scouring. In this study, the hydraulic experiment was carried out to investigate the effect of the vertical plate on the scouring charactersitics by observing the flow and sand migration phenomena in the vicinity of the vertical plate on the flat sand bed in detail. Based on the experimental result, the mechanism of local scouring was intellectualized and factors affect the characteristics of the local scouring were considered.
