摘要
Abstract
Since the analytical methods are complex in calculation and difficult to describe the complicated boundary conditions of flow systems and the structure of aquifers, a 2D profile numerical model for groundwater flow systems is established based on groundwater modelling system (CMS) software. The flow nets automatically generated in the software are employed to analyze various control factors for the structure of a groundwater flow system through a case study of the typical northern profile of Ordos Cretaceous Basin. The results show that the horizontal growth scale of the groundwater flow system is controlled by the topography (boundary conditions), and its vertical scale is dependent on the anisotropy of the aquifer. The ratio of horizontal to vertical permeability coefficient relates to the structure of the aquifer and depends on change of grid size of the model, and it has certain scale effect.关键词
