The electrical resistivity is common used in studies that intents to understand as occur the flow of water in soil and consequently as occur the groundwater recharge. The main goal of this paper is to evaluate the interference of some physical properties of the ground in the determination of the front of saturation predicted with the use of the electrical resistivity and to compare as if of the a percolating in the vadose zone, observing the variation of gotten profiles of resistivity in an interval of definitive time. Experiments were conducted in soils of southeastern complex crystalline rocks of reliance (Bação complex), within the Quadrilátero Ferrífero, Centro-Southern State of Minas Gerais, Brazil. For this experiment it was chosen two different areas by geomorphologic features. The first one is hollow on the slippery slope, with the predominance of lixisols; the second one is nose on the slippery slope, with well-developed topsoil prevalence (ferralsols). The results showed that the electrical resistivity method proved efficient for the delimitation of saturation and evaluation reloading even when it comes to subtle differences in the properties of soil water. It was also possible to establish that in the nose slope percolation is faster than in the hollow.
