Numerical simulation of sediment process and transport around radial sand ridges in coastal areas of Jiangsu Province

With respect to the sediment process of radial sand ridges in coastal areas of Jiangsu Province and key technical problems of their reclamation,the high-resolution numerical simulation of sediment transport and the isotopic geochemical tracing under the unique topographic conditions are carried out based on the large field hydrological and sediment monitoring.This study will provide necessary support for the accurate provision of the sediment transport direction and sediment discharge of the radial sand ridges,the determination of sediment sources of the radial sand ridges as well as the prediction of the effects of sediment transport on the stability of tidal flats and the operation of ports and waterways of the radial sand ridges.Finally,the technical route of the study is described,and the anticipated results are put forward.
