The hydraulic conductivity of a soil is the main parameter that determines its drainage capacity. However, its determination is of great importance for sizing in agricultural drainage systems. To determine the hydraulic conductivity of the soil in the presence of water table through the Auger-Hole. The experiment was carried out at Embrapa Manioc and Fruticulture (EMBRAPA), located in the municipality of Cruz das Almas-BA. In order to estimate the hydraulic conductivity, several empirical formulas have been proposed, such as Ernst's, which is the model that most closely approximates the soil situation studied. The hydraulic conductivity values for the studied soil obtained by the Auger-Hole method ranged from 0.24821 to 0.28544 m day -1 . With an average value for hydraulic conductivity of 0.266835 m day-¹, being considered slow. The soil under analysis is classified in slow saturated hydraulic conductivity. The Auger-Hole method proved to be practical, fast, safe and easy to handle.
