| 内容記述 | In case concrete lining canals are constructed in the sloping land, flow quickens and the bottom sediment is run. For aquatic organisms, it is difficult to inhabit. A new environment-conscious method is developed to make riffles and pools, sandbank artificially in the drainage canal which consists of concrete arms, panels and sediment. The method is making stagger patterned notches in arms. The effects of the method were verified by hydraulic experiments. These hydraulic experiments were conducted with the concrete canal which has 0.6-m wide, 0.7-m height, 50-m long, and 0.05 to 0.02 grades. The wood patterns imitated as arms were installed on the bottom of canal and sand with a d(50) of 0.054mm was laid 0.2-m thick. The discharge was set 3.8 to 5.0-l/s. Canal bed variation by the difference in bed-load transport rate was determined. The results indicate that as no bed-load transport rate, effect of the notches in arms the most greatly appeared. Therefore, canal bed was stabilized, riffle and pool, sandbank was formed. The results also indicate that as changing bed-load transport rate (by the inflow of the alternate bar), effect of the alternate bar the most greatly appeared. Therefore, canal bed was not stabilized. As an exception, if interval of the arm is set at the length of the half-wave length of alternate bar, canal bed was stabilized, riffle and pool, sandbank was formed. | |||||||||||||||||
