Based on the analysis of the field observation data off the Changjiang mouth in August 2000 and satellite image of sea surface temperature (SST) in summer of 1997, it indicates that there exists the upwelling event on the west side of the submerged river valley (SRV) off the Changjiang mouth. The calculated results of the three-dimensional nu-merical model show that this upwelling is induced by the barotropic effect, baroclinic effect, bottom Ekman effect and their interaction with the slope bottom topography. The baroclinic effect is the main cause producing the upwelling at the northern SRV (on the east side of the South Passage of the Changjiang estuary), while the barotropic effect is the main cause at the southern SRV (on the east side of the cen-ter of the Hangzhou Bay mouth). The dynamic mechanism producing the upwelling off the Changjiang mouth is differ-ent with the general one along coast and on the continental shelf.

The vertically dependent expressions of obliquely incident waves induced radiation stress are derived by use of the second order Stokes wave theory within three regions of the water column,that is,above the mean water level,below the wave trough level,and between these two *** indicate that the wave-induced radiation stress below the wave trough level is from the water wave particle velocity only,whereas both the water wave particle velocity and the wave pressure contribute to the tensor above the wave trough level;the vertical variations of the wave-induced radiation stress are influenced substantially by the velocity component in the direction of wave propagation;the distributions of the wave-induced radiation stress tensor over depth are non-uniform and the proportion of the tensor below the wave trough level becomes considerable in the shallow water;from water surface to seabed,the reversed variations occur for the predominant tensor components.

This paper focuses on the sediment transport and freshwater discharging from upper Yangtze drainage basin downstream, primarily on the basis of multiyear hy-drological data collected from three major hydrological gauge stations (Yichang, Hankou and Datong). Data indicate highest sediment load in Yichang (5.6×108 t/a), lowest in Hankou (5.1×108t) and second highest in Datong (5.4×108 t). This fluctuations are identical with what has been observed from the annual flood season. About one thirds of the sediment load are trapped in the middle Yangtze River course, where meandering river pattern prevails; rest of them are directly transported to the river mouth area via lower Yangtze River channel, where the river is typically confined by the exposed base rock and almost none is being trapped, instead, minor being drained to the mainstream from the local tributaries. To recognize this sediment delivery and river flow media is vital, because it can highlight morphologic/topographic correlation between the

On the basis of the wave action balance equation which incorporates refraction,diffraction,reflection and wave-current interaction,a directional spectral wave transformation model WABED is developed for predicting the irregular wave refraction-diffraction with strongly reflecting structures in coastal *** the model,diffraction is taken into account by introducing a term formulated from a parabolic approximation wave equation,and reflection is calculated through a back-marching numerical approach at the reflecting *** experimental data sets are used to examine the performance of present model with regard to wave characteristics around reflecting coastal *** is from a physical experiment at idealized inlet with parallel jetties,while the other is from a laboratory study on a coastal project of the concave *** good agreements are found for both cases,revealing the applicability of the present model for predicting combined wave refraction-diffraction processes with strongly reflecting coastal structures.

The shallow-water equations and pollutant convective-diffusive equation are transformed into curvilinear coordinate system. The anisotropic algebraic-stress turbulent model is introduced to simulate the turbulence items, and algebraic-stress turbulent model of planar 2-D pollutant convective-diffusive in curvilinear coordinates is build. The meandering channel with measured data of concentration in lab is adopted to validate the model, and the distribution figure of pollutant concentration field calculated through this model and that of the k-ε model, which show the model is superior to k-ε turbulent model in dealing with anisotropy character of flow.
