航道整治工程中，常采用修建整治建筑物如丁坝、顺坝等来改善河流的水深、流速、水面比降，使河流达到通航要求。

In the channel regulating work , regulating structures such as groyne , longitudinal dam are used to change water depth , water velocity and water surface slope of the channel .

拆除右岸顺坝，在左岸布置5座丁坝，利用疏浚土加高右岸遗留的下边滩和填塞原过渡航槽及下深槽。

The training dykes on the right bank were removed and five groins were arranged on the left bank , while the dredged soil was used to fill up the remained low side shoals and the transient navigation channel .

对于河流相储层，顺点坝走向或河道沉积方向注气效果好。
