| 摘 要： | 在分析磨刀门河口潮汐、水流、泥沙特性的基础上,结合2001年枯季口内灯笼山断面流量、输沙率同步实测过程线,对该断面的逐时输沙关系进行回归分析,发现无论涨潮阶段还是落潮阶段,其相关性均很高.同时通过单宽输沙量分解,对磨刀门悬沙输移主要因素进行分析,结果表明磨刀门在枯季期间以悬沙输移优势流贡献为主,悬沙向海输运.

| Abstract: | Based on the analysis of the characteristics of tide,flow and sediment at the Modaomen outlet,with the data from the synchronization time series of tidal discharge and sediment transport rate during the dry season in 2001 at Denglongshan section,it is found that there is a very high correlation both in flood tide or ebb tide stage through the regression analysis.At the same time,through the mechanism decomposition of unit width sediment flux,the main factors of suspended sediment transport in Modaomen outle... |
