Abstract
It is important to clarify three-dimensional flow structures and instantaneous vortex structures for understanding the mechanism of sediment transport and water quality exchange in spur-dike regions. In this study, characteristics of organized vortex structures around the submerged spur dikes were investigated by using PIV method. The velocity vectors were obtained in several slices of vertical and horizontal plane. The instantaneous flow structure in the region between spur dikes is quit different from the long-time averaged flow structures. The vertical vortices and transverse vortices interact with each other and the flow indicates strongly three-dimensional phase. Two-dimensional PIV analyses of vertical and horizontal planes can catch the fragment of instantaneous vortex structures.
