Sand is one of the most common materials on the earth's surface. It is a naturally occurring material resulting from the physical and chemical breakdown of rocks. Sand is derived from many rock types some of which are calcium carbonate (limestone), aluminum silicate (feldspar) or silicon dioxide (quartz).
Sand Dune Stabilization Description Sand dune areas, and steeply sloped and sparsely vegetated inland sandy areas often present challenges to site stabilization and the prevention of erosion. Coastal sand dunes are dynamic systems where sand movement is a natural process. However, construction can accelerate erosion.
