A groundwater model is a mathematical or computational representation of the physical processes that govern groundwater flow and the interactions between groundwater and other components of the hydrologic cycle. It is used to simulate how groundwater moves through aquifers, as well as to assess the quality of groundwater over time as it is affected by various factors including precipitation, land use, and potential contaminant sources.

The movement of groundwater is influenced by factors such as hydraulic gradients, porosity, and permeability of geological materials. By modeling these dynamics, one can predict how groundwater will flow in response to changes in these parameters. Additionally, groundwater models allow for the assessment of water quality parameters, including the impact of pollution, natural contaminants, and chemical interactions within the aquifer system.

This capability to predict the movement and quality of groundwater over time is critical for effective water resource management, planning, and ensuring sustainable use of aquifers. Thus, the choice that aligns with the function of a groundwater model accurately reflects its primary purpose.
