Abstract: Mathematical modelling is a fundamental tool in the study of hydrology. It allows the manipulation of certain parameters to observe their impact on different phenomena of interest and helps reduce uncertainty when making decisions during the administration of hydric resources. It is especially useful when analysing phenomena that is not so easily studied, as is the case of the hydraulic behaviour of aquifers. The objective of this work is to model the Aguascalientes Valley aquifer in Aguascalientes, Mexico, using the United States Geological Survey (USGS) MODFLOW model and the available historic data. The hydrogeologic data was collected and characterised through geographical information system tools. The numerical model aquifer was calibrated based on groundwater levels, using groundwater data from different pumping wells. The resulting model indicates groundwater overexploitation and changes in the groundwater level. This model will serve as a starting point for future water quantity and quality research on Integrated Water Resources Management (IWRM). In conclusion, the quality of data to be used in modelling plays a very important role in the robustness and reliability of the model and will determine if said model can be used to simulate specific situations of interest in different research projects. The Aguascalientes Valley aquifer model is a robust and reliable model that can be implemented for future use in hydric resource administration decision-making.
