摘要：本研究主要提出了两个针对MODFLOW模型代码的修正方案。一个修正在非饱和流动过程模拟（VSF）中增加了局部网格加密的功能扩展。这个功能扩展允许模型使用者仅在模拟区域中的特定部分内求解三维理查德方程。第二个修正引进了一个名为CFL（即阶梯流）的新程序组件。当利用Variable Saturated Flow process (VSF)或者Unsaturated Zone Flow (UZF)模块模拟地表饱和度时，它可以提高地表径流的计算精度。本文介绍并陈述了该建模的概念，并在附录中给出了程序代码文件。

Abstract: In this paper two modifications to the MODFLOW code are presented. One concerns an extension of Local Grid Refinement (LGR) to capability. This modification allows the user to solve the 3D Richards’ equation only in selected parts of the model domain. The second modification introduces a new package, named CFL (Cascading Flow), which improves the computation of overland flow when ground surface saturation is simulated using either VSF or the package. The modeling concepts are presented and demonstrated. Programmer documentation is included in appendices.
