The sand ridge field of the South Yellow Sea: Origin by river–sea interaction

Investigations of Topographic Effect on Radial Current in South Yellow Sea

“…These results indicate that: 1) before the sand ridges were generated, the sediments were carried by residual currents; 2) the original source of the sediment could be either the ancient Yellow River estuary or Yangtze River estuary. This hydrodynamic finding is consistent with the environmental magnetism results [16] and the sediment composition results [17]. Once the sand ridges had been formed, the Lagrangian residual current varied (shown in Figure 8(b)).…”

The world's largest macroalgal bloom in the Yellow Sea, China: Formation and implications

“…These sand shoals are about 200 km long and 100 km wide, and feature a pinwheel shape. These sand shoals are hypothesized to have formed from the high sediment discharges by the Yellow and Yangtze Rivers (Wang et al, 2012). The unique radial geomorphology of the sand shoals affects tidal current and result in eddies forming in the deep channels between sand shoals (Du, 2012) (Fig.…”

Risk of Surface Sediment Erosion in the Bohai Sea, North Yellow Sea and Its Indication to Tidal Sand Ridge Occurrence

“…In our case, the average erosion risk-index above 0． 5 shows a strong hydraulic regime with tidal ridge existence. In the previous study, the tidal sand ridges existing in the zone A, B, C, E, F have been widely cited ( Figure 1, Chough et al, 2002;Li et al, 2001;Liu et al, 1998;Park & Lee, 1994;Wang et al, 2012) . The recent discovered sand ridges in the Bohai Sea ( Wang et al, 2006;Wang et al, 2015 ) which are in the corresponding zone D and G in the research domain give a good proof that erosion risk might be a good clue in looking for the potential location of sand ridge.…”

“…More and more coastal engineering projects like offshore construction or seabed pipeline routing request to estimate the potential of erosion on the seafloor bottom surface, to investigate the occurrence of special bottom morphology, e. g. tidal sand ridge distribution and development along Chinese coasts ( Liu et al, 1998;Swift, 1975;Wang et al, 2012;Yang, 1989) . Considering the variety of bottom sediment types and specific sediment distribution patterns, a methodology of assessing and quantifying the status of bottom dynamics is required, studying the natural dynamics of surface sediment and its interaction with human activities.…”
