Laboratory Study of Bed Variation due to the Installation of Spur Dykes with Different Head Shapes
Based on the shapes of the spur dykes in the plan, different kinds of spur dykes can be recognized: "Straight shape or I-type", "T-type", "L-type" and etc. So far the considerable works have been dedicated to the study of the "straight" shape spur dykes, mainly aimed at investigating the flow structures around them. On the other hand, there are some limited researches and knowledge about the study of sediment transport around spur dykes with different shapes of head, especially when they are arranged in a series. In this study, the bed variation around two types of spur dykes with different shapes of head was investigated using experimental works. The equilibrium of bed variation in both spur dykes was shown and the differences and similarities of the pattern of scour hole were investigated.
