Managing the Potential Contamination of Ground Water from Pesticides

这项提案涉及的中心问题是杀虫剂对地下水系统的影响，超出了非饱和地带的地平线。这将通过将PRZM模型与3-D地下水模型正式连接来实现，并将涉及使用基于PC的GWT-平台将1-D PRZM结果空间整合到水平空间维度。这是一个为MS Windows-3编写的地下水综合模拟环境原型。它管理应用程序的所有地理、物理和化学信息的收集和使用，这些信息在屏幕上以图形模式输入。形成关系数据库，并自动用于实际模拟，在屏幕上实时监控，具有准瞬时图形输出。

The central question addressed in this proposal is the effect of pesticides on the ground water system, beyond the unsaturated zone horizon. This will accomplished by formally linking the PRZM model with a 3-D ground water model, and will involve a spatial integration of the 1-D PRZM results to the horizontal spatial dimensions, using the PC-based GWT-Platform. This is a prototype integrated groundwater simulation environment, written for the MS Windows-3. It manages the collection and use of all geographic, physical, and chemical information of the application, which is entered in graphical mode on the screen. Relational data bases are formed and, automatically used for actual simulation, monitored on the screen in real time, with quasi-instantaneous graphical output.
