Effectiveness Of Artificial Sand Dunes

Artificial Sand Dunes and Dune Rehabilitation

Clearly natural sand dunes are an effective defence against coastal flooding and erosion. However, a problem arises in that wide, sandy beaches the environment where most sand dunes occur are highly appealing for development. As such, natural sand dunes are in decline.

3. Sand dune fixation techniques

sand comes to 10 or 15 cm from their upper edge, so that they keep working effectively. Any breach in these structures can quickly set large amounts of sand in motion, again cancelling out their effectiveness. The fences are repeatedly raised until the artificial dune attains a balanced shape and thus becomes stable and fixed.

Sand dune management consists of restoring natural dune systems and processes with the implementation of “soft” technique which includes the cessation of any activity that adversely effects the sediment supply of the dunes, planting vegetation, fencing off sensitive areas, creating dune walkways, and providing information to the public regarding the importance of maintaining stable sand dunes.

Artificial Sand Dunes. Bulldozing has become a common form of artificial dune construction, in part because the vegetation/fencing approach takes some time to trap sand and build a new dune. On many beaches, bulldozers are active throughout the year in pushing up sand piles at the back of the beach. We can hardly call these sand-dike features dunes because they lack all of the characteristics
