Study of siltation for development of deep water navigtion channel of Lingdingyang in Pearl river estuary;

Analysis of reasons for the siltation in North Passage of Yangtze Estuary

Based on the understanding of the mechanism of sediment transport and channel siltation,the regulation schemes for the outer channel of Huanghua Port are evaluated,and the rationality of the regulation scheme already carried out is discussed.

Analysis of back silting of excavated harbor basin and navigation channel in silt beach of cangnan;

Based on the back silting analyses of the sandbar-dotted waterway in the Oujiang River estuary after three times dredging,reasons for back silting in the waterway are presented considering influences of flow dynamics,waves and salinity distribution on sediment concentration.

If there exists shelter embankment at the water intake area of a power plant, the back silting at the place of intake and intake canal etc.

Prediction of the amount of siltation in the seaward deepwater channel for various excavated projects is performed by using the mathematic model.

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.
