Application of Numerical Simulation in the Comprehensive Management Project of GEF Water Resources and Water Environment

摘要

with the development of computer technology, numerical simulation technology, as an effective tool for evaluation and forecast of groundwater resources, is gradually put into use at home and abroad. The paper makes use ofVisaul Modflow--a simulation software for groundwater flow and set up a 3D numerical simulation model for groundwater flow on the basis of generalizing hydrogeologic conditions to identify and verify the model by fitting flow fields and water level hydrograph, forecast tendency of groundwater level according to development and utilization plan and exploitation plan of groundwater, and provide an effective tool for comprehensive management project of GEF water resources and water environment.
