“…The sediment transport trend is found to be southeasterly at the corner of the AYRD, offshore to the northern side of AS and southeasterly in the southern side of AS. Sediment transport trend in the nearshore area agrees with the residual currents in AS (Liu et al, 2012). In AS, the trends are found to rotate clockwise from the east to southeastwards.…”

“…Preliminary estimates indicated that the volume of erosion was up to 100 million cubic meters annually (approximately 140 million t/a) in the abandoned Yellow River Delta (AYRD) area over the last 150 years. During the recent decades, most published studies had been focused on erosion (Zhang et al, 1998;Fan, 2001;Wang, 2006), sedimentary characteristics in the intertidal zone (Wang and Ke 1997; Gao, 2009a), and sediment transport of the selected areas (Chen et al, 2011;Dong et al, 2011;Wang et al, 2011;Wang et al, 2012, Liu et al, 2012. Despite the extensive studies, the sediment transport trend and spatial-temporal variability of such a huge amount of sediment transported along the entire littoral area of the AYRD are still unclear. This paper is to analyze sediment variability and transport trends of the entire littoral area of the AYRD.…”

The delta evolution and erosion process of the abandoned Yellow River Delta (AYRD) have been extensively studied. However, the variation of sediment at a large littoral scale along the north coast of Jiangsu is less understood. In this study, the data of surface sediment samples obtained in the littoral area of the Yellow River Delta in 2006 and 2012 is used to study the sediment variability and sediment transport trends by using the geostatistics analysis tool and the grain size trend analysis model. In order to ensure the applicability of the model, the geostatistics method is used to determine the characteristic distance (D c) with the average range value (Ao) of grain size parameter. Filtering method (removing data that not at a sampling station) is used to improve accuracy of data selection. The results show that sedimentary spatial correlation in Lianyun Port area and southern part of the abandoned Yellow River Delta (AS) is better than that in the northern part of the abandoned Yellow River Delta (AN). Sediment in the area is found to be anisotropy at the northeast-southeast direction. The grain size trend analysis reveals that the sediment trend is towards bayhead and southerly in the Haizhou Bay, southeasterly along the shoreline in the south Lianyun Port, northwesterly in AN and easterly-southeasterly in AS respectively. The investigation of possible relationships between D c , Ao, sediment transport and delta evolution shows a close link between D c and Ao of one sediment combination. It is also found that sediment transport trends could reasonably represent the delta evolution to a certain degree.

“…The spatial pattern of the RSRs is asymmetric characterized by northern sand ridges larger than the southern ones (Xu et al, ). The bottom sediment of the RSRs mainly consists of fine to very fine sand, with a mean grain size of 62.5–250 μm (Liu et al, ; Wang & Ke, ), and the sediment mixture is well‐sorted (Liu et al, ).…”

A Morphodynamic Modeling Study on the Formation of the Large‐Scale Radial Sand Ridges in the Southern Yellow Sea

et al. 2019

The radial sand ridges (denoted as "RSRs" hereafter) in the Southern Yellow Sea, China, are morphologically striking because of the remarkable size and radial planar orientation, standing out as a unique coastal geomorphology among the worldwide sand ridge systems. The formation of this giant fan-shaped geomorphic feature requires delicate conditions and awaits in-depth investigation. Using an idealized morphodynamic model, this study unravels the governing factors for the formation of the unique large-scale RSRs, in comparison with other types of sand ridge systems over the world. The effects of the M 2 tidal constituent, the Coriolis forcing, the bed resistance, and the initial water depths on the morphodynamic behavior of the RSRs are explored. Numerical results indicate that the tidal regime, characterized by rotational and progressive current action associated with the tidal bulge, is dependent on the eastern coastline of China as well as latitudinal effects. Through the comparison between the simulated and the measured morphology, this tidal regime is demonstrated to be the key driver in forming and maintaining the present-day RSRs. The runs with different parameters further suggest that the asymmetric pattern of the RSRs, which shows larger northern sand ridges than the southern ones, results from both the asymmetric distribution of current activity caused by the tidal bulge and unequal sediment supply. Overall, this study highlights the delicate condition, predominantly represented by the particular currents set up by the tidal wave system and the sediment supply, required to shape the striking large-scale RSRs in the Southern Yellow Sea. Key Points:• The unique giant fan-shaped morphology of the radial sand ridges (RSRs) is numerically simulated • The formation of the RSRs requires delicate conditions governed by currents originating from the rotational, progressive tidal wave system • The mechanism underlying the asymmetric spatial pattern of the RSRs is revealed Supporting Information:• Supporting Information S1

“…The distribution of SPM in satellite images is basically similar to the spread of submarine sand ridges (Figs 1 and 10). Furthermore, a previous study demonstrated that SPM concentration is low at the center of the tidal trough: medium at both sides, and high at the top of the submarine sand ridges [15]. A comparison of different images and submarine topography showed that the area of higher SPM concentration is mainly limited to within 30 m water depth, just as the distribution of sand ridges is limited to the same water depth [17].…”

“…In recent years, the evolution characteristics and transportation of SPM have become a hot topic in research on the radial sand ridges. Liu et al [15] discussed the reverse sediment transport trend between the abandoned Huanghe River (Old Yellow River) Delta and radial sand ridges. Chen et al [16] analyzed the evolution characteristics of main waterways and their control mechanisms in the radial sand ridges.…”
