The principle for designing the entrance channel of Zhuhai Port,the main design parameters concerned, line selection and the main dimensions of channel, the analysis on sandy soil in the harbour district and navigation aids are introduced in the paper.

The throughput capacity of entrance channel is an important index,which is used to evaluate whether the channel meet the need of port developing.

Research on approach channel dimension of Tianjin central fishing port and sediment siltation

Based on the well-verified three-dimensional tidal-current numerical model,the features of cross-flow in approach channel in Lianyungang Harbor were investigated.

On the basis of sediment concentration field,the annual back silting intensity on the approach channel of 70 000 DWT at Lianyungang Harbor was also simulated,and the calculated results was coincident with actual data.
