连云港近岸海域物理自净能力研究及水质预测——Ⅰ.西大堤工程对潮流场的影响

THE STUDY OF PHYSICAL SELF-PURIFICATION CAPABILITY AND THE PREDICTION OF WATER QUALITY IN THE OFFSHORE AREAOF LIANYUNGANG——I . THE INFLUENCE OF XTDABA DAM PROJECT OF LIANYUNGANG ON TIDAL CURRENT FIELD

采用有限差分解法,建立了连云港近岸海域二维固定边界和变边界潮流数值模型。分别对现状流场和西大堤建成后的流场进行计算和预测。得出了潮波图,潮流椭圆图,最大流速分布和不同时刻的流场图,计算结果与实测值吻合良好。

A finite difference technique is used to construct two-dimensional fixed boundary and varied boundary tidal current numerical models, to culculate the present current field and to predict the current field when the construction of the Xidaba Dam is completed. The fugures of tidal wave, tidal current ellipses, the distribution of maximum current speed, and the current fields at different times are obtained. The tally of computation and observation is good.
