Through the practice of several works of channel regulation,Dongying Port and the comparison with the traditional technique,the application of hydraulic sliding panel to channel debris dam are mainly introduced.

According to the siltation observation and change of sediment barrier before the integrated physical model test of the Second Stage of Sediment Barrier,Jingtang Port, the relation between the effect of project dynamic state and the moment of silty sand is initially analyzed.

This paper makes discussion on the problem of changing the shape of the armor block for the top of sediment barrier according to the practice of the east sediment barrier project of Beijing and Tangshan Port.
