The present work has two parts. The first one deals about the results obtained in the study of the water evaporation and the water movement in sandy and sandy-clay soil samples. The samples are wetted by imbibition and subjected to drying on four different evaporating demands. The accumulated evaporation of water to the end of periods of 24, 48, 72, 96, 120 and 144 hours is determined using gravimetric controls. The water mobility during the drying process is analysed by the study of the initial and final soil-water profiles. The data obtained show that the evaporation rate is greater in the sandy-clay soil than in the sandy soil, excepting to the end of the process; furthermore, the sandy-clay soil has a more adjustable water mobility.
