Abstract

Dynamical processes in the bottom boudary layer(BBL) is the key themes for energy dissipation, particulate material transport and water-sediment exchange in coastal seas. It is the important premise for environment carrying capacity prediction to get more detailed information of BBL dynamics. The development of research of BBL in the world are analyzed. It is suggested that the longterm observation based on a sea-bed triangle fram and column CTD cast in the middle of the Yellow Sea and Changjiang estuary should be carried out in order to obtain the current structure in the BBL, turbulent mixing character through the whole water column, bottom parameters like bottom roughness, friction velocity, bottom drag coeffecient, bottom particles concentration and its gredients variation. Paremeterization of dynamical processes in BBL under different conditions of tide, stratification and waves are needed to study the sediment resuspension and deposition. The influence of bottom drag coeffecient variation on tidal current and residual circulation should be studied by numerical model. It is also important to learn about the seasonal variation of particles composition and its effects on starting, resuspension and flocs. A numeircal model of particulate material transport should be used to study the sediment source and sink in the Chinese coastal water. Isotopic radiation could be used as the tracer for particle movement response to BBL processes and bottom exchange. All above are the bases for two key scientific questions we faced. One is the contribution of bottom dissipation to energy distribution in the coastal sea. The other is the multy spatial and temperal scale variation of BBL processes, particles transport and water-sediment exchange in Chinese coastal seas.
