[22] However, the presence of a Tanner gap between sand and silt (a scarcity of particles with sizes between 30 and 120 microns) suggests that different physical processes produce sand and ...

The fence is just one example of a shared expense between neighbors. Others to think about include gate considerations, fall cleanup, snow removal, land modification and vegetation planting and ...
Sand fences are employed to control erosion, help sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
