Sand fence
![Nakatajima sand dunes are located in the southern part of Hamamatsu city. The barricade fences constructed from bamboo prevent excessive drifting of the sand and thus preserve the dune area.](/Images/godic/202502/09/Nakatajima_Sand_Dunes_033609.jpg")

A sand fence or sandbreak, similar to a snow fence, is a type of fence used to force windblown, drifting sand to accumulate in a desired place. Sand fences are employed to control erosion, help sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
