1. Relative evaluation of revetment blocks by using a newly designed water courseRelative fish preference for revetment blocks was examined by using a water course which equipped two revetment block models facing each other. We found that revetment blocks have a function as a fish refuge for high velocity of over 50cm/sec. When the velocity is high, blocks with smaller opening were preferred. A block which has a slit opening at the downstream end of the block was not preferred. Emerged plants in a low velocity area are more preferred than blocks. River bank made of gravels are preferred by small fish.2. Analysis of environmental condition around the blocksVelocity, water turbulence, and other physical condition around the blocks for various flow rate were collected to build up preference curves and to calculate suitability index.3. Development of current simulation model around the blocksA current simulation model with air mixing was built. By using the model, current condition around and inside the blocks with high flow rate were calculated.4. ConclusionOur preference equation could explain the observed fish distribution when flow rate was over 50cm/sec, although it sometimes failed to explain the fish distribution in low flow rate conditions. Thus our preference equation can be used to evaluate the value of revetment blocks as fish refuge from flood quantitatively.

1。通过使用新设计的鱼类偏好对沿岸块的偏爱进行对沿岸的相对评估，并使用配备了两个彼此面对的两个cortetment块模型。我们发现，沿岸块具有高速度超过50厘米/秒的鱼类避难所的功能。当速度较高时，首选具有较小开口的块。并不是首选在块下游端的块开口的块。低速区域中出现的植物比块更喜欢。由小鱼偏爱由砾石制成的河岸2。收集各种流速的块周围的环境状况，水湍流和其他物理状况，以建立偏好曲线并计算适用性指数3。建立了围绕空气混合的BlockSA电流模拟模型的当前模拟模型的开发。通过使用模型，计算了高流速的块周围和内部的当前状况。4。结论偏好方程可以解释流量超过50厘米/秒时观察到的鱼的分布，尽管有时无法解释低流量条件下的鱼类分布。因此，我们的偏好方程式可以用来评估沿洪水避难所的供应物的价值。
