对 1 994年 8月在鸭绿江河口的水文和悬浮泥沙的观测资料进行分析。结果表明 ,在洪季鸭绿江河口的最大混浊带 ,出现在第一个河口锋面内侧。它的核心处盐度小于 1 ,从上游带入河口的细颗粒泥沙多数被河口第一锋面截留 ,还有一部分上游来沙穿过该锋面 ,聚集在河口第一和第二锋面之间。垂向密度环流作用和絮凝作用在鸭绿江洪季最大混浊带的维持过程中起着主导作用
The observed data of hydrological and suspended sediments at the mouth of the Yalu River in August 1994 were analyzed. The results show that the largest turbid zone in the Yalu River estuary of the Hong Ji appears on the inside of the first estuary front. Its core salinity is less than 1, the upper reaches of the mouth into the estuary of fine particles of sediment is the first front of the mouth of the interception, there is a part of the upper reaches of sand through the front, gathered in the estuary between the first and second front. Vertical density circulation and flocculation play a leading role in the maintenance of the maximum turbidity of the Yalu River during the flood season
