长江口深水航道数学模型信息系统研究

Study on the information system of the Yangtze Estuary′s mathematical model

利用GIS二次开发软件ArcView,完成数学模拟所需的计算网格生成及线边界法中地形数据提取的优化。集成Arc View、VisualBasic及长江口潮流数学模型,实现了数值模拟计算成果的三维可视化及实时互动的动态演示。所开发的长江口数学模型信息系统能根据整治工程需要,提交各类工程数据库。

The pretreatment of the numerical model including creating and calculating grids automatically and reading terrain information in the linear boundary technique is developed automatically by the use of the software of Arcview. Through integrating Arcview, Visual Basic and the numerical simulation model of the Yangze Estuary, the result data of the mathematical model such as tide level and velocity are visualized dynamically and interactively. The information system of the Yangtze Estuary′s mathematical model can offer different kinds of engineering databases.
