| 摘 要： | 本文对杭州湾口 1 5个测站的大、中、小潮悬沙浓度的变化规律进行了分析 ,得出大 -小潮周期流速变化和水位变化是该海区各站悬沙浓度变化的主要影响因素。通过分析研究 ,建立了单点测站悬沙浓度变化与水位和大 -小潮最大流速的关系模型 ,用该模型的计算结果与实测资料进行比较 ,拟合程度较好 ,对于整个大 -小潮周期悬沙浓度的连续变化可采用该模型进行估算。

| Abstract: | The suspended sediment concentrations from fifteen stations, observed in the mouth of Hangzhou Bay during the periods of spring, mean and neap tide, were analyzed. The results suggest that the current velocities of spring/neap cycle and water levels are main causes of sediment concentration changes at each site. The most realistic simulations were obtained when the suspended sediment concentrations were made linear functions of water levels and maximum velocity of spring/neap cycle. The concentration changes within spring/neap cycle can be obtained using the author's model. |
