“…Using the current data simulated by the Finite-Volume Community Ocean Model (FVCOM) and the predicted data for the suspended sediments in various layers of the Bohai Strait in winter over many years, the output and input fluxes of the suspended sediments were calculated quantitatively. To study the trend of the suspended sediment transport in the Bohai Strait in winter over many years, we first used the equation [22,23] (1):…”

The Bohai Strait is the only channel that allows material exchanges between the Bohai Sea and the Yellow Sea. It is also the only channel for the transportation of materials from the Yellow River to the Yellow Sea and the East China Sea. The supply of suspended sediment from the Bohai Sea plays a decisive role in the evolution of the mud area in the northern Yellow Sea and even the muddy area in the southern Yellow Sea. Previous studies have demonstrated that sediment exchange through the Bohai Strait occurs mainly in winter, but due to the lack of long-term observational data, changes in the sediment flux over multiple years have not been studied. In this paper, based on L1B data from the MODIS (Moderate Resolution Imaging Spectroradiometer) -Aqua satellite, an interannual time series of the suspended sediment concentration (SSC) at each depth layers in the Bohai Strait in winter was established through 16 cruises that benefited from the complete vertical mixing water in the strait in winter. The numerical model FVCOM, (Finite-Volume Community Ocean Model) which is forced by the hourly averaged wind field, reflected the effect of winter gales. With the model simulated winter current from 2002 to the present and the SSC at each layer, multi-year winter suspended sediment flux data were obtained for the Bohai Strait. This study found that in the winter, the suspended sediment output from the Bohai Sea to the Yellow Sea through the southern part of the Bohai Strait, while the suspended sediment input from the Yellow Sea to the Bohai Sea is through the northern part. In terms of long-term changes, the net flux ranged between 1.22 to 2.70 million tons in winter and showed a weak downward trend. The output flux and input flux both showed an upward trend, but the increase rate of the input flux was 51,100 tons/year, which was higher than the increase of the output flux rate (46,100 tons/year). These changes were mainly controlled by the increasing strength of east component of winter wind. And the weak decrease in net flux is controlled by the difference of output and input flux.

“…When the Huanghe discharged into the southern YS before 1855 AD, large amount of Huanghe derived OC could be effectively transported into site S05 in the ECS through strong coastal current along the Jiangsu coast; although site HH12 lies closer to the Huanghe estuary in Jiangsu coast, there was no current that directly transported terrestrial OC to site HH12. In addition, HH12 lies in the southern YS cold water mass which inhabits efficient transport of coastal material to the CSYSM (Zhong et al, 2020). Therefore, higher terrestrial OC contribution occurred in the SWCIM compared with the CSYSM.…”

The Huanghe (Yellow River) supplies large amount of sediments and terrestrial organic carbon (OC) to the eastern Chinese marginal seas. A relocation of the Huanghe outlet from the southern Yellow Sea (YS) to the Bohai Sea occurred in 1855 AD, however, detailed knowledge about the impact of this relocation on sedimentary source and OC burial in Chinese marginal seas is still critically lacking. In this study, we present total OC content and its isotope (δ13C), along with bulk total organic carbon (TOC)/total nitrogen (TN) molar ratio and lipid biomarker contents, in a sediment core HH12 from the southern YS with sediment age spanning the last 300 years. We find that TOC and terrestrial lipid biomarker mass accumulation rates were lower between 1855 AD and 1950 AD than that prior to 1855 AD in core HH12; and in accordance, both TOC/TN ratio and δ13C records indicate a gradual decrease of terrigenous source contributions to sedimentary OC. This suggests that the relocation of the Huanghe outlet reduced the transport of terrestrial OC to the southern YS. However, the δ13C record also indicates a relative increase of terrestrial OC contribution to sedimentary OC after 1950 AD, and the most likely explanation is increased contributions from the old Huanghe delta erosion and Korean rivers. Future studies should focus on better constraining the variations of terrestrial and marine endmembers with δ13C and Δ14C analyses of specific biomarkers to examine these linkages.

Water resources management is one of the most important issues and challenges in the world. This management may be in the form of quality management or quantitative management of water resources. Quality management of water resources is of great importance. A major problem in this case is how the input flow (for example a river) will behave when water flows to a dam reservoir or lake. Distribution of the input stream to the reservoir/lake depends on important parameters such as inflow discharge, input depth, situation and type of the reservoir outlet, type of inlet sediment , sediment concentration of inflow current and reservoir/lake , and etc. Therefore, this effect of each of the mentioned parameters on the distribution in the reservoir or lake should be examined. An important parameter that has not yet been studied is the effect of temperature of the inflow current's and the reservoir/lake's water on the distribution. For this purpose, the FLOW3D computational fluid dynamics code was selected in this study. The effect of water temperature and concentration of suspended sediment on distribution in reservoirs/lakes is considered. Several simulations with different water temperature and suspended sediment concentration values were done. Results are shown and compared each other. The results indicate the high effect of water temperature on distribution of sediments. The rising in water temperature value leads to settling the suspended sediments faster. Therefore, the temperatures of inflow and reservoir water affect the depositing and settling of suspended sediments.
