Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow, and then transported and deposited in other locations.

Erosion along limestone shores, notably in the tropics, produces karst topography that includes a sharp makatea surface above the normal reach of the sea and undercuts that are mostly the result of biological activity or bioerosion at or a little above mean sea level.

Erosion is at work while the mountains are being uplifted and long after until the mountains are reduced to low hills and plains.

Erosion rates are often monitored, and the risk is ordinarily minimized, by shaping the downstream face of the spillway into a curve that minimizes turbulent flow, such as an ogee curve.

Erosion often occurs on the outer sides of bends in river channels that wind through mangroves, while new stands of mangroves are appearing on the inner sides where sediment is accruing.

Erosion of these sediments causes the Boston Mountains to be carved steeply in the south, while in the north of the county, the Boston Mountain sediments are almost entirely eroded, exposing the older Springfield formation.

Erosion rates along the island front exceed ( and are not comparable with ) those along adjacent sectors.

Erosion usually exposes the geological formations, which are most often made of very hard and solid metamorphic or igneous rock.

The reserves are addressing water quality through intensive abiotic monitoring of estuarine habitats through the System-Wide Monitoring Program, working with farmers to develop and monitor best management practices from agriculture, monitoring the impacts of canopy cover on salmon habitats, addressing sedimentation impacts into coastal streams by working with adjacent land owners and evaluating land use impacts through tools such as the Non-Point Source Pollution, Erosion and Control ( NSPECT ) tool.

Erosion of gypsum by this underground water has caused many sinkholes, some of which have become very deep lakes that are home to unique species.

Erosion and deposition are believed to be in equilibrium in the trench.

The Towns of Brookhaven and Islip, in which the communities are located, issued bonds to pay for the project, backed by the new taxes levied by community Erosion Control Taxing Districts.

Erosion is one of two fundamental operations ( the other being dilation ) in Morphological image processing from which all other morphological operations are based.

Erosion control techniques such as windbreaks, reduced tillage or no-till, spreading straw ( or other mulch on particularly susceptible ground ), and strip farming are used to minimize topsoil loss.

" But the sea and maritime life are central to many of his poems, both short ( eg, " Erosion ," " Sea-Gulls ," " Silences ") and long, such as " The Cachalot " ( 1926 ), describing duels between a whale and its foes, a giant squid and a whaling ship and crew ; The Roosevelt and the Antinoe ( 1930 ), recounting the heroic rescue of the crew of a sinking freighter in a winter hurricane ; The Titanic ( 1935 ), an ironic retelling of a well-known marine tragedy ; and Behind the Log ( 1947 ), the dramatic story of the North Atlantic convoys during WWII.

Erosion is a common viticultural hazard with the steep vineyards because the granite and schist soils are vital in retaining heat throughout the day to protect the vines from the chilly temperatures during the mistral seasons.

Two of the more widely used methods in North America are the Revised Universal Soil Loss Equation ( RUSLE ) and Water Erosion Prediction Project erosion model ( WEPP ).

Erosion relatively quickly removes the softer minerals, and they are washed away from under the harder rock.

Erosion accelerates as the mountains rise, and great volumes of sediment are shed into the rivers, which carry sediment away from the mountains to be deposited in sedimentary basins in the surrounding lowlands.

Erosion and faulting are responsible for the mountain ’ s place in Tucson and its conical shape.

Erosion wears down the mountains and massive piles of sediment are developed in adjacent ocean margins, shallow seas, and as continental deposits.

Erosion has carved bowl-shaped cavities in many of these wind-and rain-sculpted sandstone boulders and these cavities are often filled with water ( or ice ) and algae.

Erosion is also an important control in tide dominated deltas, such as the Ganges Delta, which may be mainly submarine, with prominent sand bars and ridges.

Erosion has created the " Miramichi River valley " ( also shortened to just " Miramichi Valley "), through which the Northwest and Southwest Miramichi rivers flow.

Erosion has also played a large part in shaping the Highlands, forming extensive sedimentary deposits and wearing down the mountains.

He also continued to write and advocate regarding Federal Indian Law, publishing The Erosion of Indian Rights 1950-1953: A Case Study in Bureaucracy, 62 Yale L. J.

Erosion is also increased during rainy periods.

Erosion and soil loss on uncultivated and lightly vegetated soil ( e. g., in semi-arid environments ) may cause artifacts to also ' rise ' to the surface.

Erosion due to deforestation along the Lake as well as the Lerma River has led to increased sedimentation of the Lake, also contributing to loss of lake depth.

Erosion also increases, which can intensify flooding.

An early and prominent example of this was The Political Economy of Soil Erosion in Developing Countries by Piers Blaikie in 1985, which traced land degradation in Africa to colonial policies of land appropriation, rather than over-exploitation by African farmers.

Erosion of the southern foreshore, where the village is located, has been an important issue over recent years, this has been halted by a recent government project which installed a botan sea defence.

Erosion and glacial abrasion over the subsequent 200 million years wore away the weaker sedimentary layers, under which the sill had intruded, at a faster rate than the diabase, leaving the abruptly tilted edges of the diabase sheets exposed, creating the distinct linear ridge and dramatic cliff faces visible today.

Erosion occurring between the eruptions deposited deep layers of sediment between the lava flows, which eventually lithified into sedimentary rock.

He managed and partly owned Orange Beach Marina, served as the CEO of Coastal Erosion Control, a company that worked to prevent coastal erosion, and worked as the CEO of Escambia County Environmental Corporation, which develops landfills and waste incinerators.

Erosion allowed glacial Lake Columbia to begin to drain into what became Grand Coulee, which was fully created when glacial Lake Missoula along with glacial Lake Columbia catastrophically emptied.

In 1993, they released their second album, which was more experimental and technical, titled The Erosion of Sanity.

Erosion along the line of a geological fault known as the Campsie Fault has left tiers of rock representing some 30 lava flows which date from the Carboniferous period.

Erosion at the innerside of the ring has formed dip of about 30 m into fertile land, which gradually rises again to a central 70-m high flat-topped hill.

Erosion of citizens ' rights during World War II were upheld in the United States Supreme Court case Hirabayashi v. United States ( 1943 ), which held that the application of curfews against members of a minority group were constitutional when the nation was at war with the country from which that group originated.

* Erosion of Towra Beach due to wave refraction from the Sydney Airport runway which causes the freshwater Towra Point Lagoon to become saline

Erosion occurring between the eruptions deposited deep layers of sediment between the lava flows, which eventually lithified into sedimentary rock.
