Forty two experiments were carried out using a Guelph permeameter in old and young vines to measure the infiltration rates, the hydraulic conductivity and the soil matrix flux potential. The essays were performed before (spring-summer) and after (autumn) the harvest with dry soil conditions and without soil tillage signals, and with humid soil conditions, signals of soil farming (wheel traffic and footprints) and a decrease of organic matter, respectively. <strong></strong></p>In general, the results of the young vineyards were higher than the values of the old vineyards. Furthermore, all the rates increased after the harvest. For the young vineyards, the most elevated values were registered on the middle slope (398.5 mm h<sup>-1 </sup>infiltration rate, 89.2 mm h<sup>-1 </sup>hydraulic conductivity and 62.8 mm<sup>2</sup> h<sup>-1 </sup>soil matrix flux potential). For its part, a decrease of the infiltration from the upper slope to the foot slope was observed (from 42.5 to 16.8 mm h<sup>-1</sup>). Hydraulic conductivity and soil matrix flux potential showed the same hydro-dynamic: from 13.2 to 5.4 mm h<sup>-1 </sup>and from 5.5 to 2.5 mm<sup>2</sup> h<sup>-1</sup>, respectively. Finally, it was observed that the most correlated factor with these hydrological processes was the soil moisture content and the soil tillage practices. ER -
