Study on tidal current and sediment problems of deepwater channel project of Nansha Harbor District of Guangzhou Port;

On the relationship between maintenance condition of Yangtze Estuary deepwater channel and water & sediment transport from the valley

By use of TK-2D software,2-D tidal current mathematical model with irregular triangular grids is set up in the sea area where deepwater channel of Nansha Harbor District of Guangzhou Port lies.

Regulation principle of the Yangtze River Estuary deep channel;

Impacts of Tieji Bay reclamation project on deep channel at Sansha Bay;

By using wind,wave,tidal current,sediment numerical models based on the up-todata hydrology,sediment data of field observation and remote sensing data,sediment siltation in the deep channel is computed.

The influence pattern of deep water channels upon wave propagation is studied by REF/DIF model,which combined refraction and diffraction effects together.

Tidal current experiment and siltation analysis on deep waterway engineering of Xiamen Harbor;

Basic principles and thoughts on deep waterway regulation in the lower reaches of the Yangtze River

The prediction of backsiltation and the countermeasures against siltation in the deep waterways in the Yangtze estuary are the essential problems for the project to regulate the deep waterways in the Yangtze estuary.
