control dam 節流閘。

control experiment

In order to reduce the re - deposit volume of the dredged channel , the method must be based on decreasing the oncoming sediment , changing the mouth site , builting the sediment control dam and raising the reservoir level 為了最大限度地減小疏浚挖槽的回淤量,必須依靠控制上游來沙量、調整入水口門位置、加設防淤堤及提高庫水位等手段,而不能通過調整挖泥槽寬度、位置及數量等措施來達到目的。

In this paper , the method combined the “ s ” shape sediment control dam with the dredged channel has been put forward 為此,在比較各種疏浚方案效果的情況下,提出了挖泥槽與增設折線型防淤堤相結合的清淤疏浚措施。
