To reveal the sediment transporting mechanism between the abandoned Huanghe River (Yellow River) Delta and radial sand ridges, "End Member" Model and grain size trend analysis have been employed to separate the "dynamic populations" in the surficial sediment particle spectra and to determine the possible sediment transporting pathway. The results reveal four "dynamic subpopulations" (EM1 to EM4) and two reverse sediment transporting directions:a northward transport tend from the radial sand ridges to mud patch, and a southward transport trend in deep water area outside the mud patch. Combined with the published hydrodynamic information, the transporting mechanism of dynamic populations has been discussed, and the main conclusion is that the transporting of finer subpopulations EM1 and EM2 is controlled by the "anticlockwise residual current circulation" forming during tidal cycle, which favor a northward transporting trend and the forming of mud patch on the north of radial sand ridges, while the transporting of coarser EM3 is mainly controlled by wind driven drift in winter, which favors a southward transporting direction.
