The inappropriate land use inside the Water Recharge Areas (WRA) threatens groundwater resources. I determined all the locations with potential for groundwater recharge through soil water balance, to determinate the coefficients of soil texture (kfc), slope (Kp) and types of vegetal coverage (Kv). A Geographic Information System (GIS) generated maps for soil texture, slope, plant cover and precipitation. The over-imposed maps identified 25 WRA and their potential evapotraspiration (PET), initial humidity (Sih), humidity retention of soil, apparent density (ρa), basic infiltration of soil (fc), interception of the rain and depth of the roots that extract water. This was added to a soil water balance equation. In total, 25 WRA have an important potential aquifer recharge (Rp). This is largely due to the physical characteristics of the soil, which favor humidity retention and direct percolation. However, the WRA with little forest cover has little ability to store humidity and it is contribution is given through percolation, mainly during the rains. Forest areas stored more humidity and there is flow the whole year, even without precipitation. Rp in all areas tended to be moderate (1064 to 2073mm/year), mainly because the real evapotraspiration (RET) generated some homogeneity in the Rp. More than 23 million m3 of water are recharged in the studied area annually. |

Para determinar cuáles son los sitios con mayor potencial de recarga de agua subterránea, se realizó un balance hídrico de suelos. Los datos generados responden a los coeficientes de las variables: textura del suelo (kfc), pendiente (Kp) y tipo de cobertura vegetal (Kv). Por medio de un Sistema de Información Geográfica (SIG), se generaron mapas digitales que representan la textura del suelo, la pendiente, el tipo de cobertura vegetal del suelo y la precipitación. Los mapas se superpusieron para identificar 25 ARH, para las cuales se determinó: evapotranspiración potencial (ETP), humedad inicial (Hsi), retención de humedad del suelo, densidad aparente (ρa), infiltración básica del suelo (fc), intercepción de la lluvia y profundidad de las raíces extractoras de agua. La información generada para cada ARH, se ingresó a la ecuación general del balance. En las 25 ARH se da una importante recarga potencial del acuífero (Rp), debido en gran medida a las características físicas del suelo, las cuales favorecen la retención de humedad y la percolación directa del agua hacia un posible acuífero existente en la zona. No obstante, las ARH con ausencia de cobertura boscosa, presentan una menor capacidad para almacenar humedad y su aporte se da debido a la percolación del agua, que en gran parte se presenta cuando ocurren las precipitaciones. En las ARH cubiertas por bosque, se presenta una mayor capacidad para almacenar humedad. Por consiguiente, tanto la retención de humedad como la percolación, hacen posible el flujo de agua superficial y subterránea a lo largo de todo el año, aun cuando no ocurren precipitaciones. Los resultados de Rp en todas las ARH tienden a ser moderadamente uniformes con valores que van desde los 1064 hasta los 2073mm/año, debido principalmente a que la evapotranspiración provocó cierta homogeneidad en la Rp. En general, en el área de estudio se recargan más de 23 millones de m3 de agua anualmente.
