Introduction Numerical simulation of layered aquifer systems can involve a tradeoff between efficiency and accuracy. A traditional approach to discretizing layered aquifer systems, called the “grid overlay” method by Hoaglund and Pollard (2003), maps the heterogeneous hydrologic properties onto a rectilinear grid (McDonald and Harbaugh 1984).

Introduction Sedimentary basins are typically comprised of laterally extensive geological layers which create predictable flow regimes. However, layer discontinuity caused by structural elements such as faults, pinch outs, unconformities, and paleo-incisions can dramatically transform a groundwater flow field.
