| 内容記述 | This paper investigates experimentally the characteristics of wave-induced local scour around the rectangular column. The shape factor of rectangular column is defined as ratios of the width-thickness and the width-height. The results of local scour tests conducted under regular wave conditions show that the scour depth around the columns is governed by the defined parameters as Keulegan-Carpenter (KC) number, shape factors and the relative bottom velocity due to the initial movement of sand particles. Generally, the scour depth increases as increasing of KC number. Given a condition of waves and bottom, the scour depth increases with increasing the width and height of the column, otherwise, it decreases with increasing of the thickness of the column. The influence of relative bottom velocity due to the initial movement of sand particlees is large in case of clear water condition and becomes smaller in case of live bed condition. | |||||
