The improved fish-bone-type fishway adopts three flow rates in the hydraulic experiment—0.016cms, 0.032cms, and 0.048cms. In the sediment transport test, the tested flow rates are 0.032cms and 0.048cms. Two average granule diameters of adding sediment are 9.27mm and 10.77mm. The total experimental time is 200 minutes, with 100 minutes for adding sediment and another 100 minutes for water cleaning.

改善后鱼骨型鱼道在水理试验方面，采用三种流量0.016cms、0.032cms及0.048cms，排砂试验方面，试验流量为0.032cms及0.048cms，加砂之平均粒径为9.27mm及10.77mm两种，试验时间为加砂100分钟后，再清水冲刷100分钟，共200分钟。

This research uses the hydraulic model as an experimental tool. In different slopes (S=1/8、S=1/10), flow rates (Q=0.016cms、Q=0.032cms、Q=0.048cms), and the angles (θ=30°、θ=45°、θ=60°) of blocking pieces in the modified boat-passage fishway, the velocity and depth were measured.

本研究以水工模型作试验，藉由改变改良型舟通式鱼道之阻流材角度(θ=30°、θ=45°、θ=60°)，在不同坡度(S=1/8、S=1/10)与流量(Q=0.016cms、Q=0.032cms、Q=0.048cms)下，量测流速及水深以观测水理变化。

In the aspect of shrimp migration test, the finding reports that shrimp would use the porosity filtering to crawl towards upstream when the flow rate is at 0.001cms, and do so on the bottom of the fishway when the flow is even less.

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。

This study has three different fishway slopes(1:8、1:7、1:6), four different discharges(0.0046cms、0.0056cms、0.0068cms、0.0080cms), and six different lengths of the U-turn horizontal section(150cm、135cm、112.5cm、90cm、67.5cm、45cm).

本研究以改变鱼道坡度(1：8、1：7、1：6)、流量(0.0046cms、0.0056cms、0.0068cms、0.0080cms)及鱼道水平回头弯段长度(150cm、135cm、112.5cm、90cm、67.5cm、45cm)之条件下，进行淤砂及冲刷两种试验。
