| 摘 要： | 三门湾为一典型半封闭强潮海湾,平均潮差4.25m,湾内外水沙交换剧烈。根据2003年在三门湾水文泥沙测验、分析结果,湾口附近N1、N2、N3站所构成的断面上:(1)从大潮到小潮,流速递减;从N1站向N3站流速增加;春季,大多数情况下涨潮流速大于落潮流速。而秋季,大多数情况下涨潮流速小于落潮流速。(2)春、秋季,大小潮期间N1、N2、N3三个站上平均悬移质浓度都是涨潮大于落潮;中潮期间这三个站上平均悬移质浓度都是涨潮小于落潮。

| Abstract: | According to observation data in the Sanmen Bay in Spring and Autumn 2003,some dynamic characteristics about tidal currents and suspended load were obtained.The Sanmen Bay is a typical partly sealed and strong tide Bay,whose average tidal range is 4.25m.The exchange of the water and suspended load between inside and outside of the Bay is very strong.From the cross section of the Bay mouth N1-N2-N3.It can known that:(1) From the spring tide to neap,the current speed decreases and increases from N1 to N3;in spring,the flood speed is more than that of ebb current in most time(66%).In Autumn,the flood speed is less than that of ebb current in most time(66%).(2) In Spring and Autumn,during the spring and neap tide the averaged concentration of suspended load in flood current is more than that in the ebb current;while during the middle tide the averaged concentration of suspended load in flood current is less than that in the ebb current. |
