| Research Abstract |
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
