The purpose of fishway is a way for fish to migrate upstream through dams and other obstructions.

中文摘要鱼道的目的在为使鱼类能溯上水坝、急流或其他水流障碍物而设计之通道。

Tumbling flow is appeared in this fishway which produces wave surge and continues to flow downward and may causes serious damage due to its behaviour of periodic tumbling action.

在这种鱼道中出现的滚动流将产生波涌，并继续向下传播，而且它的周期性滚动可能会严重危害鱼道。

In the past, SWCB had once organized several related biological corridor engineering including fishway and pathway in bank revetment et al., however, due to the engineer designer only poorly experience in fishway design, the past engineering should be considered more space to progress.

过去水保局亦曾经规划与兴建不少相关的生物廊道工程，包括鱼道与护岸生物通道等工程，但是有不少工程规划设计人员因为经验不足，所设计的工程仍有进步的空间。

The U-turn horizontal section of a fishway can slow down the flow velocity, elevate the water depth and provide the rest space for fish.

在鱼道内设置水平回头弯段之目的在於减缓流速、抬高水深及提供鱼类休息空间。

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。

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。

Fish migration, especially for smolts protected by law, will be influenced; hence a physical fish screen made of fixed meshed with 1 cm2 holes and provision of bypass channels are necessary.

其中，鱼类洄游，特别是受法律保护的二龄鲑，将会受到工程影响，需要安装网格为1 cm2的护鱼筛网并提供鱼道。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
