As the interstice of a wind break or hedge causes wind path, the wind velocity increases and wind erosion is often promoted.
According to our investigation, the accelerated wind velocity at the interstice within a shelterbelt reached to about 120% of standard velocity. It was found that Sodegaki which was slanted off from the artificial hedge was more effective than the right-angled one.
On the occation when the hedge were pierced with a road, the zigzaged Sodegaki was most effective and the blowing through the interstice was ceased.
