At what wind speed does soil movement typically begin?

Soil movement typically begins at a wind speed of around 13 miles per hour. This threshold is significant because at this speed, the force exerted by the wind can dislodge and lift small particles from the surface of the soil, initiating sediment transport. Understanding this wind speed is crucial for managing erosion and accurately predicting dust-related issues.

When wind speeds exceed 13 miles per hour, the potential for soil erosion significantly increases, especially in arid and semi-arid regions where soil is more susceptible to being carried away due to lack of moisture cohesion. By knowing this threshold, erosion control measures can be more effectively planned and implemented, helping to mitigate the environmental impact of wind erosion.
