摘要

为给河口整治提供参考和借鉴,基于DELFT3D模型系统建立了长江河口水沙数学模型,并利用实测水文、泥沙数据进行了率定、验证。大量实测资料验证结果表明,该模型的潮位、潮流和含沙量模拟平均精度分别可达91%,86%和72%,模型具有较好的模拟精度。该模型在长江河口治理规划研究、整治工程方案设计、施工设计、航道治理等方面应用效果良好,可为相关整治工程的决策和设计提供一定的技术支撑,值得进一步推广应用。
        In order to provide reference and guidance for regulating river estuary,we built a tidal flow and sediment numerical model for Yangtze River estuary based on DELFT3D model system. Based on the measured hydrology and sediment data,the model was calibrated and verified. The verification results of a large number of measured data showed that the average accuracy of tidal level,tidal current and sediment concentration simulation can reach 91%,86% and 72% respectively. The model has good simulation accuracy and performs well in the application of Yangtze River estuary regulation planning,project design,construction design and regulation of river channels. This model provides technical support for the decision-making and the design of such regulation projects,which is worthy of further promotion.
