Abstract: With the development of social, economic, groundwater pollution is becoming a concern in our country. In view of the defiency of traditional finite difference method, in this paper, a proposed hybrid finite analytic method was adopted to solve the problem about groundwater pollution. Testing with some examples and contrasting with finite difference method, we can get the conclusion that the hybrid finite analytic method is available.

Abstract: In view of the problem that the predictive results of flow quantity are not ideal for the predictive models at present. Based on the chaos identification to the flood system, chaos BP neural network model are developed combined chaos theory and BP neural netwok, flood sequences are disposed by phase-space reconstruction to be as training sample. Network structure can be determined by Matlab toolbox. The established chaos BP model is used to predict the phenomenon of peak value for Huayuankou hydrometric station in 2006. The results show that the predictive model combined chaos theory and BP neural network, has certain reference value to improve flood forecasting accuracy as a new attempt.

Abstract: In order to visualize the water control planning, optimization of Matlab is embeded into VB programe. Friendly man-machine interface can easily realize the integration of data analysis and water pollution control optimization which can form the visualization software related to water pollution control programs. Examples are shown that combination of the two programmes can greatly enhance the grade and accuracy of planning to improve the work efficiency. The potential applications of the combination of VB and Matlab are discussed in final discussion.
