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.

为了最大限度地减小疏浚挖槽的回淤量，必须依靠控制上游来沙量、调整入水口门位置、加设防淤堤及提高库水位等手段，而不能通过调整挖泥槽宽度、位置及数量等措施来达到目的。
