| dc.description.abstract | The U.S. Geological Survey modular groundwater model (MOD FLOW) by McDonald and Harbaugh ( 1988) implements a finite-difference technique in its numerical scheme. Because of this, the spatial discretization of the flow domain in two-dimensions is limited to rectangular cells. This paper presents a package that adapts MODFLOW' s numerical scheme into a non-generalized integrated finite-difference technique which allows flow to be simulated through a curvilinear grid. The curvilinearity is discretized into piecewise linear segments which creates a two-dimensional grid with trapezoidal cells. The new model is termed MODIFD: A Modular Three-Dimensional Integrated Finite-Difference Groundwater Flow Model. The modifications made to the source code of MODFLOW are documented in Appendix A. | |
