To investigate the effects of groynes on the Shigenobu River innorthwestern Ehime Prefecture, a field investigation was conducted to measure the sizes of groynes and the sizes of stones on the surface of the groynes as well as the bed morphology around the groynes. Numerical analyses of the three-dimensional flow and bed variation around the groynes were conducted. It was found that the bed variation around successive groynes was affected by the particular arrangement of groynes. The study proposes a simple arrangement of river structure for stable bed morphology

为探讨石坝对爱远县西北部重根武河的影响，通过野外调查，测量了石坝的大小、石坝表面的石块大小以及石坝周围的河床形态。通过数值分析，对坝体周围的三维流动和床层变化进行了分析。研究发现，连续的砾岩周围的层位变化受砾岩的特殊排列方式的影响。该研究提出了一种简单的河流结构安排，以稳定河床形态
