韩江-榕江-练江三江水系连通工程调水水流可视化技术研究及应用

Research and Application of Visualization Technology of Water Diversion in Hanjiang-Rongjiang-Lianjiang River Water System Connectivity Project

在三江连通工程的基础上,通过对水流数据处理、水流演进展示技术的研究,提出了以数据清洗、标准入库及结构化组织为主要内容的水流数据处理流程并根据水流要素的不同分类确定了多种要素展示技术,最后结合调水实例对水位和流速进行可视化展示。研究表明,三江水流可视化技术渲染速度快、视觉内容丰富,为三江水系连通效果和决策评估提供良好支持。

On the basis of the Hanjiang-Rongjiang-Lianjiang river connectivity project,through the research on the flow data processing and the flow evolution display technology,this paper creatively proposes the flow data processing with data cleaning,standard storage and structured organization as the main contents,and determines the display technology of various elements according to the different classification of the flow elements,and finally visually displays the water level and flow velocity in combination with water diversion examples.The research shows that the visualization technology of the dynamic evolution of Hanjiang-Rongjiang-Lianjiang river is fast in rendering and rich in visual content,which provides good support for the connectivity effect and decision evaluation of the Hanjiang-Rongjiang-Lianjiang river system.
