山溪性强潮河口围垦工程对潮流的影响

Influences of reclamation in a hilly, fluvial and macro-tidal estuary on tidal flow

本文以山溪性强潮河口———鳌江河口为例 ,采用平面二维有限元数学模型模拟计算不同水文条件下鳌江口外南岸边滩围垦前后的区域潮波与潮流变化分布。据此 ,分析了围垦工程对山溪性强潮河口潮流的影响。

A hilly, fluvial and macro-tidal estuary, Aojiang estuary, was taken as an example here to study the influences of reclamation in this kind of estuaries on tidal flow, where a 2-D finite element numerical model was established to simulate the hydrodynamic situation and the distribution of change in tide and tidal flow under different hydrological conditions after the reclamation in the southern marginal bank outside Aojiang estuary was calculated.
