WAN Xin-ning，LI Jiu-fa，HE Qing，SHEN Huan-ting. REVIEW OF SUSPENDED SEDIMENT FLUX IN THE WORLD[J]. Advances in Earth Science, 2002, 17(6): 864-870.
The progress of the suspended sediment flux in the world is reviewed in this paper, the methods of researching in theory, simulation experiment, mathematical modeling, hydrological, mechanism analysis and field measurement with the advanced instruments have been adopted to study the suspended sediment flux. The transportation of the suspended sediment in the estuary mainly studied the vertical distribution of suspended sediment concentration and lopsided transportation. The physical models are intuitive, but limited by the scales and precisions of the models and lack of suspended sediment models. The mathematical models can provide qualitative products due to their speed and veracity. The transportation of the suspended sediment, especially the spatio-temporal distribution of the sediment, which can be studied with the traditional hydrological method under the different dynamic factors in the estuary. The mechanism analysis is a mature and credible method, but lacking in combing with the dynamical mechanism and the suspended sediment transportation in the estuary. The field measurement with the advanced instruments is affected by the precision of the instruments and the setting points. As a result, many things of suspended sediment flux need to be done thoroughly.
