ABSTRACT
Groundwater modeling refers to the construction and operation of a model that can mimic the actual behavior of groundwater in an aquifer system. There are several kinds of groundwater models: electrical analog, physical (most physical models look like ant farms packed with layers of sand and clay), and mathematical. For this primer, we use “groundwater model” to mean a mathematical model. A mathematical model is a set of equations and assumptions chosen to represent a groundwater system. Computer programs then solve these sets of equations.
