120MF/10  Sabaudia, Lungo

120MF/10 Sabaudia, Lungomare, 2017 Le dune di Sabaudia con la particolare flora e la finissima sabbia bianca, visibili gi dal lungomare. Durante i mesi estivi soprattutto intorno alle spiagge che si concentrano le attivit turistiche, dove si susseguono esclusive strutture balneari, ristoranti all'aperto e splendide ville private. Il litorale tuttavia ha mantenuto il suo aspetto naturale, anche per la presenza di lunghi tratti di spiaggia libera e per la possibilit di accedere all'ampia battigia attraverso passerelle di legno, che permettono di attraversare la fitta macchia mediterranea. The dunes of Sabaudia with the particular flora and the fine white sand, visible even from the seafront. During the summer it is mainly around the beaches that the tourist activity is concentrated, where there are exclusive seaside resorts, outdoor restaurants and beautiful private villas. The coast, however, has kept its natural appearance, also due to the presence of long stretches of free beach and the access to the wide shoreline through wooden walkways that allows to cross the dense Mediterranean scrub.

This is the beautiful vie

This is the beautiful view from the top of the Dune du Pyla in France. We were there to watch the sunset. On the one side we had an amazing overview over the see with a beautiful sunset. But if I looked to the other side, I was overwhelmed by the endless wood of pinetrees! I saw nothing else there, just green until it touched the blue horizon far away. Allthough many tourists were behind me, watching the sunset, an amazing silence lay over these big trees and for a few seconds I forgot complete that I was surrounded by talking people, it had something magical.Anyway, I watched the sunset but I didn't forgot the feeling of pure nature I had for a few seconds. These moments are rare and special, we have to enjoy every single one of them!

An extract on #dune

Some coastal areas have one or more sets of dunes running parallel to the shoreline directly inland from the beach. In most cases, the dunes are important in protecting the land against potential ravages by storm waves from the sea. Although the most widely distributed dunes are those associated with coastal regions, the largest complexes of dunes are found inland in dry regions and associated with ancient lake or sea beds. Dunes can form under the action of water flow (fluvial processes), and on sand or gravel beds of rivers, estuaries and the sea-bed. The modern word "dune" came into English from French c. 1790, which in turn came from Middle Dutch dne.

Crescent-shaped mounds are generally wider than they are long. The slipfaces are on the concave sides of the dunes. These dunes form under winds that blow consistently from one direction, and they also are known as barchans, or transverse dunes. Some types of crescentic dunes move more quickly over desert surfaces than any other type of dune. A group of dunes moved more than 100 metres per year between 1954 and 1959 in China's Ningxia Province, and similar speeds have been recorded in the Western Desert of Egypt. The largest crescentic dunes on Earth, with mean crest-to-crest widths of more than three kilometres, are in China's Taklamakan Desert.

Fixed crescentic dunes that form on the leeward margins of playas and river valleys in arid and semiarid regions in response to the direction(s) of prevailing winds, are known as lunettes, source-bordering dunes, bourrelets and clay dunes. They may be composed of clay, silt, sand, or gypsum, eroded from the basin floor or shore, transported up the concave side of the dune, and deposited on the convex side. Examples in Australia are up to 6.5 km long, 1 km wide, and up to 50 metres high. They also occur in southern and West Africa, and in parts of the western United States, especially Texas.

Straight or slightly sinuous sand ridges typically much longer than they are wide are known as linear dunes. They may be more than 160 kilometres (100 miles) long. Some linear dunes merge to form Y-shaped compound dunes. Many form in bidirectional wind regimes. The long axes of these dunes extend in the resultant direction of sand movement. Linear loess hills known as pahas are superficially similar. These hills appear to have been formed during the last ice age under permafrost conditions dominated by sparse tundra vegetation.
