We measured the in situ suspended sediment concentration (SSC) and hydrodynamics (waves, currents, and sea level) concurrently during a storm event using self-recording instruments at offshore of the Shandong Peninsula in the Yellow Sea. We analyzed the temporal variation in suspended sediment carrying capacity and its correlation with wave, current, and water-level conditions. There was about 40% increase in SSC during the storm event. A 3-4-h lag was observed between the peak of wave height and SSC. The SSC increased in a fluctuating pattern up to the peak then decreased rapidly. This process was positively correlated with wave height and duration. The maximum SSC was 524.3 mg/l, which is about 10 times of that under normal weather conditions. This peak was observed after of a series of 1.8 m waves. The increased suspended sediments were the fine particles resuspended by the storm waves from seabed near the observation spot and transported by northward ebb currents from Shidao Bay.
我们在风暴事件期间使用自记仪器在山东半岛附近的黄海海域同步测量了原位悬浮泥沙浓度 (SSC) 和水动力（波浪、水流和海平面）。我们分析了悬浮泥沙携带能力的时间变化及其与波浪、水流和水位条件的相关性。在风暴事件期间，SSC 增加了约 40%。在波浪高度峰值和 SSC 之间观察到约 3-4 小时的滞后。SSC 呈波动模式增加至峰值，然后迅速下降。这一过程与波高和持续时间呈正相关。最大 SSC 为 524.3 mg/L，约为正常天气条件下的 10 倍。该峰值出现在一系列 1.8 米高的海浪之后。增加的悬浮泥沙是由风暴波从观测点附近海底重新悬浮的细颗粒物质，并由石岛湾的北向退潮流输送而来。
