Sand dune stabilization

Sand dune stabilization is a relatively basic and common form of soft coastal engineering. It involves the planting of vegetation to stabilize and protect sand dunes along the coastline. The creation of artificial dunes is also considered to be an effective form of soft coast engineering protection, particularly in conjunction with shore nourishment. 

Slope stabilization is just one potential application for composites in the broad area of erosion control. Several other related applications are bridge abutments, freeway cuts, storage tank embankments, mine tailings, sand dunes, and areas of turbulent water flow.

Artesian conditions require that there be a confining bed and elevated heads elsewhere in a groundwater recharge zone, (a) Shows elements of a "classical artesian system within a syncline. Artesian wells are shown in (b) stabilized sand dunes, (c) crystalline rock, (d) folded and fractured sedimentary rocks, (e) flat-lying sedimentary rocks, and (f) glacial sediments. From S. N.

Fencing. The use of relatively porous barriers to stop or divert sand movement, or to destroy or stabilize dunes. Cheap, portable and expendable structures are desirable (using, for example, palm fronds or chicken wire)... 

Eolian plains (planicies eolicas) plains covered by sand and silt, which were deposited by wind during the Pleistocene in the Llanos, eolian plains with stabilized Pleistocenic dunes more than 10 m high are distinguished from completely flat eolian plains covered by silt strata. These plains extend principally from the southern central Llanos to the lower Arauca-Cinaruco basins in the west Llanos.
