| 摘 要： | 以乐清湾海区特征测站实测资料为据,运用机制分解法将悬沙净输移通量分解成多个动力项并讨论不同区域悬沙输移的时空分布特征,认为潮泵输沙在湾内贡献均较大,在浅滩附近占明显优势,垂向净环流输沙在小潮期中,内湾作用显著,平流输沙在开阔水域及中湾深槽起主要作用.从余流分布、流速与含沙量的相位关系、垂向余流结构与悬沙浓度垂向梯度变化...

| Abstract: | According to the measured field data in Yueqing Bay,the transport flux of suspended sediment in observed stations is divided into several dynamic items using the mechanism decomposition method,and the space-time distributional characteristics of suspended sediment transport is examined.It is indicated that the tidal pumping effect plays an important role in the bay and especially has a clear superiority in shallow regions.The vertical circulation causes prominent sediment transport in middle and inner bay d... |
