ABSTRACT

In designing group groynes, the space of the groynes is an important factor, and the flow between the groyne areas will vary along the space. Since the flow in the groyne field significantly affects the flow change, the bed change, the bank erosion and the condition of the habitat, an assessment of the flow along the space of the groynes will yield important data needed to diversify the object of the groyne installation. To provide basic data for the determination of the proper space of groynes in a groyne group, the flow in the channel and groyne field, which varies with the installation of the groyne, is herein analyzed. The space of the groynes was set from the same length to 12 times the length of the groyne, and the flow range was measured using the LSPIV method and ADV. The influence of the angle of the installation was also analyzed. As a result, through the flow configuration in the groyne field and the flow range at the center of the groyne field against the space of the groyne, the decreasing influence of groyne erosion was suggested by the analysis of the shelter effect of aquatics and the countercurrent in the bank line.
