Water Quality Prediciton System Of Rural Small Water System Based On Engine ArcGIS Technology

In recent years,the problem of water environment pollution has become more and more prominent,which has caused people's extensive concern,and makes people fully aware of the importance and urgency of protecting the environment.In the people's attention and expectations,water quality simulation technology has made great progress.The mathematical model of water quality can be on different types of environmental problems and water pollutants transfer and transformation process and spatial distribution of calculation and simulation analysis,but based on the obtained results usually does not support visual function and spatial information management is a difficult problem.The current geographic information system technology(GIS)can effectively deal with the above problems,so the water quality simulation technology and GIS technology in the analysis of water pollution and water quality simulation and other work will have a wide range of application prospects.This paper in Jixian,Tianjin Hao door village surrounding water as the carrier,of one dimensional steady water quality model,two-dimensional steady-state attenuation tired and mixed flow model and GIS integration technology were studied and discussed.To successfully create a reasonable discretization water quality model,the numerical calculation results and the simulation results are able to clearly show,in this study,intends to discrete calculation of river,one dimensional River take block generalization approach and by using the two and three-dimensional River grid processing.Using oriented object Java programming tools and GIS ArcGIS Engine control,the water quality simulation module of the user interface and convenient operation,successfully resolved the problem of water quality simulation results cannot be displayed,in addition to effectively highlight the GIS spatial data integration,query,management and analysis application function.In Jixian County,Tianjin,wear Fang Yu Zhen in trench gate in the village of random discharge water quality prediction simulation analysis of users set their own conditions of water quality real-time simulation study,effectively improved the water quality model is practical,can respond to environmental emergencies,trench gate in the village of integrated control and management scientific quantification,provides technical support and guarantee.In this paper,Water quality prediction and forecasting results visualization significantly improve the water quality prediction of intuitive,raise the efficiency of environmental management.The results of the final model in the form of contour and the velocity field in the visualization of GIS platform,has obtained the good effect of visual display.
