VAZQUEZ-GUEVARA, Luis Gerardo et al. Evaluación de la vulnerabilidad del acuífero Victoria - Güémez mediante el método DRASTIC. Geofís. Intl [online]. 2023, vol.62, n.2, pp.467-485.  Epub May 31, 2024. ISSN 2954-436X.  https://doi.org/10.22201/igeof.2954436xe.2023.62.2.1589.

Studies about water in aquifers are limited, and scarce in the state of Tamaulipas. For this reason, the objective of this work was to evaluate the intrinsic vulnerability of the Victoria-Güémez aquifer using the DRASTIC method and the WaterYield modeler of InVEST 3.7, which considers biophysical data of the soil and plants, to estimate with greater precision the factor of recharge. The results obtained made it possible to identify that the highest vulnerability of the aquifer occurs in and around the urban areas with the largest surface area, while the lowest occurs in areas with a high depth of the water table and low permeability in the vadose zone. This study is the first step to generate a groundwater management tool in which the lines of action are established to manage the water of the aquifer that is in deficit.
