黄河三角洲的悬浮泥沙提供了重要的物理、地质和地球化学信息。一个时间序列的波，电流，浊度，温度和潮位测量超过134天的时间内使用潜艇部署的三脚架。建立了波高、流速和悬沙浓度相互作用的静态模型（多元线性回归）和动态模型（叠加锯齿模型）。结果表明，该地区的悬浮泥沙浓度较高，平均为2.24 g/L。建立了波浪和水流共同作用下的锯齿形悬沙浓度叠加模型。剪切应力的结果解释了如何幕波负责大锯齿形状和电流占小锯齿形状。
ABSTRACT Sediment suspended in the Yellow River delta provides significant physical, geological, and biogeochemical information. A time series of waves, currents, turbidities, temperatures, and tide levels were measured over a 134-d period using a submarine deployed tripod. A static model (multiple linear regression) and a dynamic model (superposed saw-tooth model) were constructed to express the interactions among wave height, current velocity, and suspended sediment concentration. The results documented a high suspended sediment concentration in this area with a mean of 2.24 g/L. A superposed saw-tooth model of suspended sediment concentration disturbed by waves and currents was developed. The shear stress results explained how episodic waves were responsible for the big saw-tooth shape and how currents accounted for the small saw-tooth shape.
