- Approach the method of habitat restoration for Macroinvertebrates on Fixed River covered with Concrete
説明
<p>Although there were lots of papers about setting spur dikes, none of them clear the characteristics about sediment transportation and deformation of river bed around spur dikes on the Fixed Bed. In this study, investigation of Ikejiri River, which had been set up spur dikes three years ago, and flume experiments were conducted in order to consider the suitable methods of setting spur dikes in restoration for Macroinvertebrates. The comparison of the experimental results, we could indicate three key points about construction: 1) They aren’t attracted sediment transportation well between spur dikes, so it’s better to set sediment there artificially 2) The submerged spur dikes should be set up three and more continuously, 3) The only first interval between spur dikes should be narrows.</p>
