ABSTRACT
Analytical equations (Theis and others) are commonly used in groundwater hydrology as predictive simulators. Here, these analytical equations and numerical models such as the MODFLOW ‹nite-difference groundwater ¡ow model and the MT3DMS modular three-dimensional transport model are referred to as S models. Their user’s manuals and many groundwater hydrology, hydraulics, and modeling references provide simulation modeling details.
