In quantitative study of the interaction between the lake water and groundwater, the hydraulic conductivity of lake bedsediment is a very important parameter.
在湖水与地下水相互作用的定量研究中，湖底沉积物的渗透系数是极其重要的参数之一。

In order to prove the effects of the sediment transport of the project scheme, comparative experiments of fixed bedsediment transport before and after regulation were made.
为了进一步论证工程方案的泥沙输移的效果，还进行了整治前后定床输沙对比试验。
