| 摘 要： | 建立了长江大通至河口大范围的一、二维嵌套水流盐度数学模型,其中大通至江阴采用一维河网数学模型,江阴至口外段采用一般曲线坐标系平面二维数学模型.采用长江大通至江阴以及江阴至河口段的实测资料对建立的一、二维模型进行了较系统的率定,结果表明:数学模型计算与实测资料均吻合较好,验证了该数学模型运用于长江口水流盐度数值模拟的可靠性,为下一步进行长江口盐水入侵研究奠定了基础.

| Abstract: | 1-D and 2-D coupling flow and salinity mathematical model is established,in which Datong to Jiangyin reach is simulated by 1-D model, and Jiangyin to estuary reach is simulated by 2-D model respectively.1-D river-net mathematical model and 2-D horizontal mathematical model in generalized curvilinear coordinate are established respectively; and then 1-D and 2-D models are coupled. The established 1-D and 2-D models are calibrated by field data from the Datong to Jiangyin reach and the Jiangyin to estuary reach.The calculated results are show that the established model is reliable;so that it can be used to simulate the rules of flow and salinity at the Yangtze River Estuary. |
