| 摘 要： | 分别于1986年12月和1985年3月1日—1987年3月1日在海州湾进行了波浪和含沙量观测，运用所获资料以及本区长期水文、地形资料，采用流体力学、沉积学和泥沙运动力学相结合的研究方法，建立了海州湾淤泥质海滩剖面堆积过程的二维计算模式。结果表明，在堆积型淤泥质海滩，由于浮泥的经常性存在，使波浪急剧衰减，其对岸滩的作用甚为微弱，潮流成为塑造淤泥质海滩的主要动力，岸滩在淤涨过程中，在平均高潮位厂沿和平均低潮位附近出现两个凸点，上一个凸点外推速率大于下一个凸点，潮下带变化缓慢。

| Abstract: | This paper reports results of studes on the mud flat of data obtained inHaizhou Bay. On the basis of field surveys of wave and sediment in December, 1986,and from March lst 1985 to March 1st 1987, and on the characteristics of hydrology,morphology in this area, a two-dimension model describing the ascretion of theHaizhou Bay, was established by combining knowledge of hydraulics, sedimentologyand sediment kinematics. The results showed that tide crrrent played a dominant rolein changes of the accretion mud flat; that waves are weakened sharply by the nearbottom suspended mud; and that its contribution to the shore is weak. In the accretionprocess of the mud flat,two convex points appeared : which one at the bottom of themean high water the other near the mean low water. The accretion of the former wasfaster than that of the latter. The subtidal zone accretion process was much slower. |
