A concrete ramp should follow the natural profile of the beach to prevent it from changing the normal flow of waves, longshore currents, water and wind. Fabric ramps are commonly employed by the military for temporary purposes where the underlying sediment is stable and hard enough to support the weight of the traffic. The former are described in detail below; the larger geological units are discussed elsewhere under bars. While the destruction of flora may be a gradual process that is imperceptible to regular beach users, it often becomes immediately apparent after storms associated with high winds and freak wave events that can rapidly move large volumes of exposed and unstable sand, depositing them further inland, or carrying them out into the permanent water forming offshore bars, lagoons or increasing the area of the beach exposed at low tide. A foliage ramp should require minimal maintenance if initially formed to follow the beach profile, and not overused.

A beach is a landform alongside a body of water which consists of loose particles. Wild beaches can be appreciated for their untouched beauty and preserved nature.

Concrete ramps are the most expensive vehicular beach accesses to construct requiring use of a quick-drying concrete or a cofferdam to protect them from tidal water during the concrete curing process. Get kids back-to-school ready with Expedition: Learn! Over long periods of time, these influences may substantially alter the shape of the coastline, and the character of the beach. Beach nourishment is the importing and deposition of sand or other sediments in an effort to restore a beach that has been damaged by erosion. Not to be confused with: beech – tree with light colored bark and edible nuts: We planted beech trees in the front yard.

Sediment moved by waves or receding floodwaters can be deposited in coastal shallows, engulfing reed beds and changing the character of underwater flora and fauna in the coastal shallows. A foliage ramp is formed by planting resilient species of hardy plants such as grasses over a well-formed sediment ramp. Runoff that is dispersed along the beach will tend to percolate through the beach and may emerge from the beach at low tide.

Foreign unwashed sediments may introduce flora or fauna that are not usually found in that locality.
Brighton Beach, on the south coast of England, is a shingle beach that has been nourished with very large pebbles in an effort to withstand the erosion of the upper area of the beach. Significant erosion of the sediment beside and under the corduroy can render it completely ineffective and make it dangerous to pedestrian users who may fall between the planks. The line between beach and dune is difficult to define in the field. These measures are often associated with the construction of structures at these access points to allow traffic to pass over or through the dunes without causing further damage.


Beachfront flora plays a major role in stabilizing the foredunes and preventing beach head erosion and inland movement of dunes. They may also have hospitality venues (such as resorts, camps, hotels, and restaurants) nearby. Erosion of beaches can expose less resilient soils and rocks to wind and wave action leading to undermining of coastal headlands eventually resulting in catastrophic collapse of large quantities of overburden into the shallows. Some beaches have man-made infrastructure, such as lifeguard posts, changing rooms, showers, shacks and bars. Its form and dimensions depend on a number of factors, such as wave Some minor relief forms are usually present on the surface of sand beaches. Often the water outflow proceeds in the form of linear Beach sands in temperate latitudes consist mainly of Sometimes the basement layers of the beach are cemented by calcium carbonate, precipitated from the groundwater.

Wild beaches, also known as undeveloped or undiscovered beaches, are not developed in this manner. Longshore currents will tend to replenish beach sediments and repair storm damage. Beach material often originates from erosion of nearby cliffs or is supplied by gravel rivers draining nearby mountains.

beach (bēch) n. 1.

Concrete stairs are commonly favored on beaches adjacent to population centers where beach users may arrive on the beach in street shoes, or where the foreshore roadway is substantially higher than the beach head and a ramp would be too steep for safe use by pedestrians. On sandy beaches, the turbulent backwash of destructive waves removes material forming a gently sloping beach.

In many places the concentrations are so great that they are of industrial significance; placer deposits are worked in India, Brazil, Japan, Most beach materials are the products of weathering and erosion.
