永定新河口通海航道形成水动力泥沙研究

根据规划永定新河河口拟建一条通海航道,利用了该海域的现场实测资料对水动力条件、地质分布、泥沙特性以及淤积等水动力泥沙特征进行了分析,建立了风浪、潮流和泥沙数学模型,对该航道开挖后的年淤积情况进行计算预测。通过与其临近港口的比较,提出了该航道形成可行性依据,为该航道工程的建设提供科学依据。

Study on Hydrodynamic & Sedimental Characteristics for a Seaward Channel Formation in the Yongdingxin River Estuary

According to the determined plan,a sea-connecting channel will be built in the Yongdingxin River estuary.The in situ measurement data from the sea area are used to analyze the hydrodynamic conditions,the geological distribution,the sand and mud features,the mud deposition,and other characteristics.Mathematical models are set up respectively for wind waves,tidal current,and sand transport to calculate and forecast the annual mud deposition in the post-formation of the channel.After the modeling results are compared with the conditions of the adjacent harbours,the feasibility reasons are described for the channel formation,laying a scientific foundation for the channel engineering and construction.
