Abstract: Despite the importance of water on earth, little is known about its dynamics in the soil, and consequently, there is little information about its preservation in quantity and quality. Therefore, the objective of this research was to generate information to support the understanding of water dynamics in soil springs in recharge areas. Thus, we carried out monitoring flow and precipitation in the areas of two belonging clearance, verifying the relationship between the physical and water attributes of the soil closely related to groundwater recharge, in addition to soil characteristics, land use, cover vegetation and slope. The results showed that the signaling that Cambisoils have higher infiltration capacity and consequently clearance in relation to Latosols was not confirmed in this study. Even though there is a large discrepancy in relief classes between the recharge areas of springs, this effect was not sufficient to reduce the recharge process. Land use conditions were not substantially different as to influencing the infiltration process. The big difference between the recharge areas of the springs on the ability to generate runoff base is explained by physical-water attributes and rainfall, which in this case resulted in a more effective association in the area of ​​spring L1. The higher water retention capacity of the Oxisol, reflecting the higher microporosity associated with its greater depth, is an unfavorable feature for the recharge process, when compared to Inceptisol, which has an incipient B horizon and lower depths.
