Flat coast

At the flat glide or flat shoreline, the land descends gradually into the sea. Flat coasts can be formed either as a or situation. of the sea advancing into gently-sloping terrain or through the abrasion of loose rock. They may be basically shared up into two parallel strips: the shoreface in addition to the beach.

Flat coasts consist of loose fabric such as sand as well as gravel. Wind transports finer grains of sand inland over the dunes. The sea washes pebbles and sand away from the coast and dumps it at other locations.

Beach losses and gains

Beaches are normally heavily eroded during storm surges and the beach grouping steepened, whereas normal wave action on flat coasts tends to raise the beach. not infrequently a whole series of parallel berms is formed, one gradual the other. There is a consequent unhurried increase in height with the sum that, over time, the shoreline advances seawards. A striking example of land-forming system of berms is Skagen Odde on the northern tip of Vendsyssel in the extreme north of Denmark. This headland is still growing today as more berms are added.

Coastal defences against erosion are groynes, stone walls, or tetrapods of concrete, which act as breakwaters. The first plants to colonise the dunes put sea buckthorn or beach grass which prevent wind erosion.
