Abstract Wind erosion is a problem not only in the arid and semi-arid parts of the Earth but also in the temperate climates. Long-term wind erosion of plots decreases the nutritional content and deteriorates the upper soil’s physical properties. Shelterbelt planting and plot size planning are effective tools for wind erosion control. Our new method combines two already existing model functions to determine the effect of erosion length and windbreak systems on wind erosion hazard potential: the WEPS windbreak subroutine and the TEAM length factor function. By combining the windbreak subroutine and length factor, a new GIS tool was developed which easily modelled the windbreak system airflow control and erosion length effect of the potential wind erosion hazard. A strong (15 m/s at 10 m height) wind event was modelled, and it was found that the windbreak system could decrease the deflation potential. Significant result was the extent to which erosion length and windbreak systems influenced the potential wind erosion hazard. In the study area, the simulations showed that the windbreak system had a greater influence on potential wind erosion control than plot size. This paper’s main contribution is to demonstrate how windbreak system planting and plot size and shape planning can influence wind direction distribution and draw attention to the role of preventive agriculture management in controlling wind erosion hazard areas.
