Smith Faculty of Agriculture, Food and Environment.</div><div><br></div><div>***Purpose of the test campaign***</div><div>The purpose of these experiments was to investigate the effects of time-dependent contact angle on water infiltration into subcritically water-repellent soils.</div><div><br></div><div>***Test equipment***</div><div>The contact angle was measured for sessile drops placed on uncoated, ethanol coated and oleic acid–ethanol solution-coated glass beads using a goniometer (EasyDrop DSA20E, Hamburg, Germany). Infiltration experiments for three glass beads were carried out in 60 cm glass-bead column under ponding condition with a constant water head of 3 cm.</div><div><br></div><div><br></div><div>***Description of the data in this data set***</div><div>The data included in this data set has been organised as:</div><div><br></div><div>Figure 1.
