Beach transfer

from Wikipedia, the free encyclopedia

As beach displacement is sediment transport by sea designated by the loose material (such as sand ) favored by maritime parallel flows and obliquely to the beach blowing winds along the coast will be transported so that sand walls, spits and sand hook arise typical characteristics of a graded shoreline .

From the prevailing wind direction, the waves are thrown diagonally onto the beach; the water runs onto the beach. The ground friction causes the water to lose momentum until it comes to a standstill. Under the influence of gravity, the water flows off again in the downward direction.

The sand grains transported by the water follow the movement of the water, they are carried along the beach in a zigzag movement, wave by wave. In the slipstream and slipstream of islands, gravel and sand are deposited ( accumulation ) and so-called sand hooks are formed. Such sand hooks grow into elongated spits after a long time. When a spit completely cuts off a bay, a freshwater lake is created behind it.
