Effects of Flow Circulations on the Sediment Dynamics in the Deep-water Navigation Channel of the Yangtze River Estuary

Journal of Coastal Research (2020)

Xu, H.-J,; Huang, Z.; Bai, Y., and Bai, Y.-C., 2020. Effects of flow circulations on the sediment dynamics in the Deep-water Navigation Channel of the Yangtze River Estuary. In: Malvárez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 723a-727a. Coconut Creek (Florida), ISSN 0749-0208.In this paper, a two-dimensional model is established to estimate the hydro-sediment dynamics in the Deepwater Navigation Channel of the Yangtze River Estuary by calculating the flow field and sediment deposition. The results show that the circulation is mainly caused by shear stress of the flow in the main channel during the maximum flood and ebb tides and that at these times, the circulations are small and close to the groyne roots. At the slack tides, the water level gradient is an indispensable factor, and the circulations are relatively larger and located in the center of the groyne fields. The spatiotemporal characteristics of the sediment dynamics are considered closely related to the flow circulations. Specifically, the flow circulations inhibit the scouring of the groyne fields because these circulations form areas with low flow velocities and an enclosed environment that prevents powerful flow of the deep-water channel into the groyne fields. The results will provide effective support for the safe operation of the Deep-water Navigation Channel in the Yangtze River Estuary.

A Theoretical Model to Predict the Critical Hydraulic Gradient for Soil Particle Movement under Two-Dimensional Seepage Flow

Water (2017)

Zhe Huang Yuchuan Bai Haijue Xu Yufen Cao Xiao Hu

The soil particle movement under seepage flow is one of the predominant mechanisms responsible for incidents and failures of dams and streambanks. However, little attention has been paid to the critical hydraulic gradient under two-dimensional (2-D) seepage flow. In this study, a theoretical model was established under 2-D seepage flow to predict the critical hydraulic gradients for soil particle movement. In this model, the sediment particle rolling theory was used, while taking into account the relative exposure degree of the soil grains and the seepage direction. The model was validated through qualitative analysis and comparison with previous data, and showed considerable superiority over Terzaghi's model. In addition, the effect of the soil internal instability, implying that the critical hydraulic gradient of unstable soil is lower than that of stable soil, was discussed. Various parameters of the model were also analyzed. The results showed that the seepage direction angle was positively related to the critical gradient, whereas the void and the mean diameter of the soil were negatively related to it. Finally, the model proposes a calculation method for the particle movement initiation probability, which is regarded as a key parameter in the sediment transport model.
