摘　　要：外海围涂工程的实施将导致临江江道水动力环境发生改变。应用平面二维潮流数学模型,基于无结构网格,采用有限体积法,计算鳌江口外围涂工程实施后鳌江江道内潮量、流速、水位等水文要素的变化。数学模型计算结果显示,工程的实施将引起鳌江水位、流速和进潮量的变化,水位降低,进潮量减小,但未引起河势较大的变化。Implementation of offshore reelmnation project will result in changes of riverside hydrodynmnic environment. Based on tmstructtn＇ed grids and finite volume method, a 2D horizontal current naathematical model was used to calculate the hydrological elements variation such as tidal volume, velocity, water level of the Aojiang River after implementation of Aojiang estuary outer reclamation project. The study shows that water level, flow rate and inlet tidal volume of Aojiang river changed ＇after reclamation, both water level and inlet tidal volume decreased, but the reclamation did not cause large changes in river regime.
