用建立的珠江三角洲航道网一维水流模型提供边界,在白坭重点整治河段应用二维潮流数值模型进行计算,采用实测资料进行验证。研究河段工程前后的水位、流场、近岸流速及水流动力轴线的变化,分析回答工程后航道整治效果、工程对河势的影响。 Using the established one-dimensional flow model of the Pearl River Delta waterway network to provide the boundary, the two-dimensional tidal current numerical model is applied to the key river regulation section of Baijiu River. The data are verified by the measured data. The changes of water level, flow field, nearshore flow velocity and hydrodynamic axis before and after the river section engineering are studied. The effects of the waterway improvement effect and the project on the river regime are analyzed and analyzed.
