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

<div>Schematic diagram of the groove changes from the semicircular shape to the rectangular shape. (r), (h), and (l) represent the radius of the semicircular shape groove, the height of the rectangular shape groove, and the length of the bottom side of the rectangular shape groove, respectively.</div>
