In particular, the hydraulic behavior of a fault zone will depend on different factors, such as the percentage of clay within the fault core (Apaydin, 2010), the structures of the damage zone which is defined as an area with densely fractured rocks in the vicinity of the fault, which can greatly improve permeability and consequently the flow of fluid through the area's (Caine et al., 1996) activity or inactivity, the age, the potential dissolution or precipitation of chemical substances transported by the flowing water, and the stress regime to which the structure is subjected (Hernández-Marín and Burbey, 2009; Hernández-Marín et al., 2017). However, these factors that define a particular hydraulic fault's response are difficult to quantify. One of the techniques that provide qualitative elements for defining the hydraulic behavior is the mapping of parameters measured in the groundwater, which can reveal anomalous variations across a fault zone. For instance, recent investigations in predicting the hydraulic properties of the fault zone are employed by different investigators (i.e., Bense et al., 2003, 2008; Anderson and Fairley, 2008), in which the authors based their research on the elaboration of detailed profiles. These profiles show anomalies of the hydraulic heads and geothermal variations. These investigations employ critical values of 4 ^∘C for geothermal variations and 10 m for hydraulic heads; the changes define the faults as a barrier or conduct. The analysis of hydraulic-fault response based on graphical representations can give an overview of the hydrological conditions around several faults, where the parameters measured in the groundwater, combined with the available geological information on the area, can better explain the observed variation in the hydraulic properties of failures. The objective of this work was to perform a two-parameter graphical-correlation analysis that characterizes the hydraulic behavior of the faults regarding temperature and hydraulic heads. This analysis provides a better understanding of the aquifer system of the Aguascalientes valley.
