The Design And Development Of East Lake Water Quality And Water Environment Platform Based On EFDC

In recent years,urban lake pollution is increasingly serious,water quality worrying.Most of the traditional lake governance is treated after the pollution occurs,which not only requires a lot of manpower and material resources,but also difficult to achieve results in a short time,the use of water quality model to simulate the migration of pollutants,and simulation results are visualized,To provide support for the management of urban lakes,the governance time ahead of the outbreak of pollution before,will be of great significance.To this end,this paper analyzes the EFDC(The Environmental Fluid Dynamics)model,GIS(Geographic Information System)technology,WCF(Windows Communication Foundation,Windows Communication Development Platform)technology and WPF(Windows Presentation Foundation,Windows Presentation Foundation)Based on these four techniques,the Dadong Lake water quality ecological environment analysis platform based on EFDC model is constructed,and the visualization of each index point and the animation simulation of lake pollutant migration process are realized.Since the EFDC model was created,through domestic and foreign research institutions and organizations for more than 20 years of research and application,it has been the continuous development and improvement,and hundreds of cases at home and abroad have been successfully applied.With the development of computer software,distributed technology is a comprehensive and efficient use of resources has been recognized,and WCF as a new software development architecture is also widely used with the IT industry.This paper based on the characteristics of EFDC model,and the open source EFDC model,the three-dimensional hydrodynamic and water quality numerical model of Dadong Lake water system in Wuhan City was established.The water quality and water environment analysis platform was developed with WCF technology,GIS technology and WPF technology.This paper analyzes the whole process of platform construction,analyzes the integration process of EFDC model,the service-oriented advantages of WCF technology and the application in this platform,and implements the process of pollutant migration in GIS technology,and analyzes the whole process of platform construction from the system server and client.Animation simulation method,WPF technology in the development of interactive friendly interface in the use.The main findings obtained include:First,the EFDC model for the first time applied to China's largest city lake-East Lake,,and the advantage of the EFDC model is used to provide a new theoretical support for the Dadong Lake water system.Second,follow the trend of the development of computer software,different from the traditional stand-alone version of the water quality simulation tool,based on WCF technology to achieve the platform of the distributed architecture;Thirdly,from the perspective of user experience,it has overcome the shortcomings of most water quality simulation tools interface,combined with WPF interface development technology,developed a good interaction,beautiful client interface;Fourthly,the ArcGIS WPF API is used to simulate the process of pollutant migration,which provides intuitive and vivid support for Dadong Lake water pollution control scheme demonstration.
