Coastal sand dunes develop on coastlines with an adequate supply of material within the size range 0.2-2.0mms. The critical factor is the availability of a sufficiently large beach, which dries out at low tide and where sand grains are blown onto the land by the action of the wind.Sand dunes occur in many parts of the World, along coasts and in deserts. In most locations in the temperate regions of the world, vegetation plays an important role in the growth of the typical dune landscape, which is so familiar to anyone visiting the 'seaside', by facilitating the accumulation of sediment.
