查询词典 turtle crawl

但水流在鱼骨型鱼道中流况非常紊乱，故考虑在鱼骨型鱼道之主要支干上加一多孔隙滤材(本文称改良后鱼骨型鱼道)，使水流较趋於稳定，水中鱼类更易於上溯外，更让虾类藉以攀爬至防砂坝上游繁殖。

试验结果显示，在水理试验方面，改良后鱼骨型鱼道水位皆比原鱼骨型鱼道高，流量则比原鱼骨型鱼道低，显示多孔隙滤材能有效改善流况；排砂试验方面，泥砂约於时间第30分钟即达到输砂平衡，排砂率在97％以上，残留於鱼道之泥砂为3％以下，证明增设多孔隙滤材并不影响其排砂率；鱼类上溯试验方面，粗首鱲於试验时间内，上溯率达73％以上，皆比原鱼骨型鱼道为高，显示改良后鱼骨型鱼道更适於鱼类上溯；而溪虾上溯试验方面，发现溪虾於流量0.001时，藉由多孔隙滤材向鱼道上游攀爬，再由量更小的情况下，溪虾便由鱼道渠底向上游攀爬。
