In the areas of low coasts the sea deposits sediments that it carries from the continents, carrying through a work of construction called sea accumulation. The beaches, the reefs and restingas are formed from the work of sea sedimentation. Pluvial erosion the pluvial erosion is the work executed for waters of rains in the surface of the Land, cause consumes of the ground dragging the materials composes that it. Rain is one of more active the erosive agents, and when falling on one definitive area it can open small holes until great craters in the ground, as well as says War (1998, p.165): ' ' The resultant processes of the pluvial erosion closely are related to some ways taken for the water of rain, in its ticket through the vegetal covering, and to its movement in the surface of solo.' ' The erosion caused for waters of rain goes to vary as the aggression of the destructive force of waters, with the duration of rains and type of ground. The impact of the drops d' water on the ground to provoke the disaggregation of the added torres and in a known phenomenon as salpicamento.

In a rainy event the waters of rain can fall directly in the ground when in it has vegetation, they can fall on the pantry of the trees or more drain for the trunk of them and leves, arriving the form surface branda. When it arrives at the ground, it can infiltrate in the fretico sheet or if move for the surface causing erosion.
