码头前沿水域潮流观测与分析预报的应用

为满足当前港口工程对精细化潮流预报的需求,通过比较准调和分析、流体动力——数学模型、最小二乘法三种潮流预报方法,认为最小二乘法的调和分析方法最为适用于小尺度水域的潮流预报。该方法选择以定点及漂流观测获取码头前沿水域的实测流况资料,通过分析实测资料,了解所在水域的潮流特征,再结合最小二乘法调和分析,对前沿水域进行定点的潮流预报。

Application of Tidal Current Observation and Prediction to the Water Area in Front of Wharf Apron

To meet the nee prediction, three methods d of the present harbor engineering for precise tidal current including quasi-harmonic analysis, fluid dynamic-mathematic model and least square method have been applied to predict the tidal current in the water area in front of the wharf apron. By comparing the three methods, the least square method holds the best for the tidal current prediction in the small-scaled water areas. By means of this method as well as by analyzing the data observed both at fixed stations and by the way of drifting, the prediction of tidal current has been made for the fixed sta- tions in the water area in front of the wharf apron.
