| 内容記述 | The amounts of suspended matter and benthic macroinverbrates swept by an experimental riverbed leveling work were investigated in the middle reaches of the Shinano River. The concentration of suspended solid (SS) was 8.43 mg/L at the four study sites on the day before the beginning of the riverbed leveling (Day -1), but it increased up to 115.53 mg/L at the site 200 m downstream from the working site (St. 2) on the day of the beginning of the work (Day 0). Ash-free dry mass of the SS showed that inorganic matter content accounted for 84.4% of the SS at St. 2 on Day 0 and was much higher than Day -1 (72.9%). The most abundant particle size class of SS at St. 2 on Day 0 was 1-75 μm, followed by ＜1 μm, and inorganic particles of 1-75μm size class were the most abundant component swept by the leveling work. Down stream drift of benthic macroinvertebrates was mainly composed of Chironomidae, Oligochaeta, Ephemeroptera and Trichoptera at the study sites both on the Days -1 and 0. The drift densities of Oligochaeta and Chironomidae were 0.15 and 0.54 ind./㎥ at St. 2 on Day-1, but on Day 0, they increased up to 143.0 and 45.9 ind./㎥, respectively. The benthic macroinvertebrates swept by the riverbed leveling work were suggested to be flown away at least 1 km downstream from the working site. | |||||||||||
