NUMERICAL TESTS FOR SOIL EROSION REDUCTION SOLUTIONS UNDER THE ACTION OF THE WIND

The purpose of this study is to make a numerical model of air movement over a sandy terrain provided with protective screens. This model was based on a series of physical tests on air flow in a wind tunnel with discontinuity, for which velocity profiles were obtained in different sections downstream of the air inlet. Following the numerical simulation of the air flow under the same conditions as those of the physical tests, almost identical velocity profiles were obtained in the same sections. This allowed the validation of the numerical model and its adaptation to simulate the movement of air in the atmospheric boundary layer zone above a sandy terrain provided with a number of permeable protective screens with the aim of reducing the wind speed.
