Wind Erosion Control

short-windbreks-and-h-persicum
Sand dunes fixation: Stabilizing a dune to control the sand movement can be accomplished chemically, mechanically or biologically. Stabilization control measures could be temporary or permanent. A temporary sand control system is used as an initial stage during the application of a permanent one. A temporary system may include shielding the ground with stable material or erection of fences or other methods. Shielding the ground can be accomplished by stone mulching, wetting, chemical stabilizers, biological crusting or covering the ground by any other material such as tree branches, sheets, nets, geo-textiles, or similar materials. The erection of fences can also temporarily control sand hazard. – https://exmediablog.files.wordpress.com/2016/07/short-windbreks-and-h-persicum.png?w=940
