| 中文摘要: |
| 应用Delft3D研究了珠江口最大浑浊带的分布以及影响因素。盐度和悬沙浓度的垂向分布揭示出最大浑浊带范围的变化。最大浑浊带在干季的悬沙浓度比湿季更大,而其中心位置与湿季相比向上游移动10 km。最大浑浊带的形成受到潮汐、径流和地形的综合影响,而沉积物的再悬浮和垂向环流为影响最大浑浊带的主要因素。 |
| 英文摘要: |
| Real-time observations in the field and numerical simulations (with Delft3D) were combined to study the formation, distribution and the relevant influencing factors of turbidity maximum (TM) in the Zhujiang (Pearl River) Estuary (ZE). The spatial distribution pattern of the TM varies with the longitudinal distributions of salinity and suspended sediment concentration (SSC). The SSC is enhanced and the TM is intensified during dry seasons, whereas the center of the TM moves upstream by a distance of 10 km during wet seasons. The formation of the TM is influenced by a complex combination of numerous factors, including tides, river discharges and topography, wherein sediment resuspension and vertical circulation dominate the formations and variability of the TM. |
