NUMERICAL SIMULATION OF WAVE-INDUCED NEARSHORE CURRENT
Wave Nearshore current Mathematical model Rectangular grid Triangular grid
2013/7/22
In this paper, a mathematical model of wave-induced nearshore current based on the radiation stress theory is improved both in theory and in numerical technique. The work in three aspects has been don...
DISTRIBUTION AND DIFFERENT FORMS OF PHOSPHORUS IN SEDIMENTS FROM THE CHANGJIANG ESTUARY AND HANGZHOU BAY
Sediment Phosphorus Form Grain size Distribution
2013/7/22
This paper studies the distribution and different forms of phosphorus in sediment collected from the wastewater discharge outfalls in the waters adjacent to Shanghai. The results show that the average...

2013/7/22
Based on the simulated current fields under different layouts offered by numerical models, the Liu Formula Cao and Formula, which have been widely used in the sedimentation engineering, are adopted to...
WIDENING RATE OF ESTUARINE REGULATION AND ITS PRELIMINARY CALCULATION IN THE TRAINING LINE OF NORTH DEEP-CHANNEL OF THE CH ANGJIANG RIVER ESTUARY
Widening Rate Changjiang River Estuary Estuarine Regulation
2013/7/22
Based on the morphological relationships of rivers and estuaries, a formula for calculating widening rate of training works in estuaries has been derived. The widening rate is related to dimensions of...
MODEL STUDIES ON LOCAL SOCUR IN THE REGULATION PROJECT OF THE DEEP CHANNEL IN THE CHANGJIANG ESTUARY
Local scour Groins and jetty Model test Changjiang Estuary
2013/7/22
The local scour of the 1st-phase regulation project of the deep channel in the Changjiang Estuary were experimentally studied. The local-scour pits around head of the groins and the north jetty were s...
STUDY ON THE POSSIBILITY OF OCCURRENCE OF FLUID MUD IN THE YANGTZE DEEP WATERWAY
Yangtze Estuary Fluid mud Deep waterway regulation Nautical depth
2013/7/22
Generally there is a higher sediment deposit rate in the navigation channel on muddy coasts so that the constant dredge is necessary. This usually means more expenditure of the port operation in those...

Changjiang estuary Deep waterway Back-siltation
2013/7/22
In describing sediment back-siltation in the Changjiang estuary, China, this paper reports the three steps of navigation channel project and two major reasons of sediment back-siltation during the fir...
SEDIMENT TRANSPORT OF SEA-ENTERING WATERWAY IN THE CHANGJIANG ESTUARY
Changjiang Estuary Sea-entering waterway the Basic Laws of Sediment Movement
2013/7/22
As is known to all, the mouth bars reach is a key section to the deep waterway improvement in the Changjiang Estuary with sediment erosion and deposition. Evolution of the mouth is very complicated i ...
