Design And Implementation Of Groundwater Information Management System

Groundwater is an important part of water resources. In north China and many cities, groundwater is acted as the major water resources supplier and plays an important role for the implementation of local economy and society. So it is an urgent affair to accelerate the establishment of groundwater management towards modernization and informatization. The implementation and application of groundwater information management system would provide technical support not only for the realization of groundwater dynamic monitoring, investigation, evaluation, sustainable utilization, optimized configration and the management level, but also for the real-time decision of water resources utilization and configration.In this paper, firstly the present situation of the domestic and overseas researches of the hypogeal water information management system is expatiated on, then the function structure of the system is designed, the function requirement of each sub-system, the computation of resource capacity and the hypogeal water parameter, the secondary implementation based on component, the dynamic forecast model of hypogeal water, and the four special requirements of automatic creation of isoline are clearly analyzed and described. On the basis of the researches mentioned above, the structure of the system and the database are designed, and the environment of the system network, and the environment of the implementation and the function are discussed: The implementation of this system chooses the structure of C/S as the similar three-layer structure and modularized ways of implementation. The method of relation model is adopted to create four application RDS. finally the main function as the following, four special requirements of the system, the collection of secondary estimate, the hypogeal water inspection information management system and the hypogeal water resource forecast and warning are implemented.Through the systematic realization and actual application, this system achieved the following function: the automatic computation of groundwater resources quantity and hydor-geological parameters, the automatic summarizing of the second-round evaluation products, the real-time inquiry and the visible show, the management and analysis for maps, the statistics and analysis and the water-level forecast of groundwater information, the management of spatial and attribute information of the groundwater monitoring wells, and the auto-generating of contours.
