内容記述(抄録等)Though the local scour take rise by change of sediment transported through each section, generally, it is so complex phenomenon that the change of flow character in scour hole is closely related to progress of scour, and the development of scour is defined by changed flow charactor. According to investigation on the sediment motion and the flow character by observations with moter-drive camera, on the scour mechanism, the progress of local scour from submerged plane jets are distinguished in three stage; i.e., initial, interium and progressive. In initial stage, the scour take rise in the sediment transport depends on the location from plane wall-jet. After the scour change to interium, the flow separate from sand surface at an inclined plane downstream of scour hole. The scour change into progressive stage, in addition to the separation of flow, the intermittent collapse of a slope downstreams of scour hole becomes occour. In this paper, the author describes the results of some experiments on the scour from submerged plane jet, and suggest the method analysed the development of scour hole. As a results of analysis, it becomes clear that the separation of flow and the intermittent collapse are important in order to explane the mechanism of the local scour from submerged plane jet. The experimental results can be analysed sufficiently by the method proposed here.
