MORPHOLOGICAL RESPONSE OF ESTUARIES TO NODAL TIDE VARIATION
Westerschelde Humber estuary Sediment budget Nodal tides Modelling Field observations
2013/7/22
Nodal tide variation causes a periodic change of the mean tidal range with a period of 18.6 years and amplitude of about 4%. As the cross-sectional area of the channels in estuaries is related to the ...

OCEANIC DIFFUSION VIEWED THROUGH THE DYE DIFFUSION STUDY
Oceanic diffusion Dye diffusion Horizontal diffusivity Hydraulics
2013/7/22
Slug dye diffusion study to obtain the horizontal diffusivity was often carried out in Japan in 1960s to 1970s. The data of these studies are reviewed. Also, several methods to obtain the oceanic dif...
MATHEMATICAL MODELING OF MORPHOLOGICAL CHANGE AT A RIVER MOUTH
River mouth Sand spit Migration, Mathematical model
2013/7/22
A mathematical model for calculating river mouth width is introduced, by considering sediment intrusion by waves, as well as sediment flushing by river and tidal discharge. Behavior of an analytical s...
NEW DEVELOPMENT IN NUMERICAL SIMULATION OF THE TIDAL BORE
The Qiantang River Godunov scheme Tidal bore Numerical simulation Moving boundary
