What Is Groundwater Modeling?

An object or structure made based on the characteristics of an actual groundwater system that reproduces or replicates the actual groundwater flow system or process state. It is a substitute with characteristics of groundwater systems. The groundwater system is abstracted. According to the similarity in mathematical form between the groundwater system and the model, a set of mathematical relations is used to characterize the quantitative relationship and spatial form of the physical processes occurring in the actual groundwater system. According to the similarity between groundwater and other physical phenomena, the model made from groundwater problems to similar physical problems is called "groundwater physical model". According to the nature of the groundwater flow problem represented by the model, it can be divided into water volume model and water quality model. The groundwater model can be used to solve many hydrogeological problems, such as the evaluation of groundwater resources and the movement of pollutants in groundwater.
