摘要: A computer program for simulating ground-water flow in three dimensions is presented. This report includes detailed explanations of physical and mathematical concepts on which the model developed. Ground-water within aquifer simulated by using a block-centered finite-difference approach. The written Fortran 77 has modular structure, permits addition new packages to without modifying existing packages.
