Resumen:
The investigation involves a temporal and spatial analysis to
characterize recharge in the Aguascalientes valley in central Mexico.
The results are based on a two-part methodological strategy using a
geospatial and numerical analysis. Results from the geospatial analysis
are based on the analytical hierarchical process (AHP) method, which
involves developing a zoning map that qualifies the conditions for
groundwater recharge in the valley. In addition, one-dimensional
numerical modeling based on the van Genuchten equation was applied for
various soil column configurations to estimate the transit time of
recharge through the vadose zone. The analysis was performed over a
20-year period from 1995 to 2015. The results of the geospatial analysis
indicate that the optimal area for groundwater recharge is the lower
zone of the valley, particularly the portion influenced by surface
discontinuities. The shortest estimated period of recharge for water to
pass through the vadose zone is approximately 4.25years.
