Numerical Investigation of Wind Erosion to the Grooved Concrete Wall Surface under a Wind-Blown Sand Movement

<div>Wind erosion rate distribution on the two different grooved wall surfaces at the impact angle of 45° and wind velocity of 23 m/s: (a) side views of erosion rate distribution on the grooved wall surface which contains a semicircular shape groove; (b) side views of erosion rate distribution on the grooved wall surface which contains a rectangular shape groove.</div>
