The study looked at how sparse windbreaks can protect oases by slowing down wind speeds and causing sand to settle. By using wind tunnel simulations and calculations, the researchers found that the spacing between windbreaks is crucial in controlling wind speeds to prevent sand erosion. They also discovered that the density of windbreaks affects their protective effects. Overall, the study shows that carefully planning the layout of windbreaks can help conserve water resources and safeguard vulnerable areas from desertification.
