江苏沿海四港感潮河段非汛期水沙运动特点初探
Preliminary study on flow and sediment transport characteristic of tidal reaches of four coastal channels in Jiangsu Province in non-flood period
摘要
Abstract
In order to study the flow and sediment transport characteristic in tidal reaches of four coastal channels ( Sheyang River, Huangsha channel, Xinyang channel and Doulong channel) in Lixiahe area of Jiangsu Province in non-flood period, the tidal level, tidal current and tidal sediment discharge during spring, middle and small tide under different open-close operation modes were monitored. The results show that tidal level difference of open mode is lower than that of close mode;the tidal level difference of night tide is higher than that of solar tide in middle and spring tide;the sediment transport rate of Sheyang River is significantly higher than the other three; the suspended sediment concentration in ebb tide is significantly smaller than that in flood tide;the flood-tide duration is much longer than the ebb-tide duration.关键词
