 note = {To predict and control sediment transport and water quality exchange by using submerged spur-dike, it is necessary to clarify three-dimensional flow structures and instantaneous vortex structures around spur-dike zones. In this study, relative height of super dike to water depth is chosen as a design parameter and its effects on flow structures in spur-dike zones are investigated by using PIV method. Two-dimensional PIV analyses of vertical and horizontal planes reveal the time-averaged flow structures in spur-dike zones with reasonable accuracy.The vertical vortices caused by the top flow and transverse vortices caused by the side flow interact with each other and produce characteristic three-dimensional vortex structures. The vertical profiles of the longitudinal velocity indicate similarity with respect to the top level of the spur dike. The inverse flow strength becomes larger at an inner part of the spur-dike zone with an increase of the relative height., application/pdf},
