Groundwater sapping is causing this gully to lengthen up the slope. Image Cox Lavaka W16.jpg thumb right Active headwarderosion lavaka on right, with inactive, largely infilled older examples to left Headwarderosion is a fluvial process of erosion that lengthens a stream , a valley or a gully at its source river or stream head and also enlarges its drainage basin . The stream erodes away at the rock and soil at its headwaters in the opposite direction that it flows. Once a stream has begun to cut back, the erosion is sped up by the steep gradient the water is flowing down. As water erodes a path from its headwaters to its mouth at a standing body of water, it tries to cut an ever shallower path. This leads to increased erosion at the steepest parts, which is headwarderosion. If headwarderosion continues long enough, it can cause a stream to break through into a neighboring drainage basin watershed and stream capture capture drainage that previously flowed to another stream.

Erosion corrosion is a degradation of material surface due to mechanical action, often by impinging liquid, abrasion by a slurry, particles suspended in fast flowing liquid or gas, bubbles or droplets, cavitation , etc. The mechanism can be described as follows mechanical erosion of the material, or protective or passive oxide layer on its surface, enhanced corrosion of the material, if the corrosion rate of the material depends on the thickness of the oxide layer. The mechanism of erosion corrosion, the materials affected by it, and the conditions when it occurs are generally different than that of flow accelerated corrosion , although the last one is sometimes classified as a sub type of erosion corrosion. Surface chemistry can play a role in erosion corrosion due to Mechanochemistry mechanochemical effects.

Unreferenced date December 2009 Internal erosion of soil particles from within a dam by water that seeps through the dam is one of the most common causes of failure of levee s and earth dam s. Internal erosion is especially dangerous because there may be no external evidence, or only subtle evidence, that it is taking place. Usually a sand boil can be found, but the boil might be hidden under water. A dam may breach within a few hours after evidence of internal erosion becomes obvious. Internal erosion manifests by the migration of soil particles by suffusion or piping . Piping is induced by regressive erosion of particles from downstream and along the upstream line towards an outside environment until forming a continuous pipe. Suffusion is the migration of soil particles through the soil matrix.

Gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. Some drugs, as tablets, can irritate this mucous membrane, especially drugs taken for arthritis and muscular disorders, steroids , and aspirin . A gastric erosion may also occur because of emotional Stress medicine stress , or as a side effect of burn s or stomach injuries. Symptoms There is basically one symptom of gastric erosion bleeding from the area where the stomach lesion is. Bowel movements may contain blood . Vomit may be bloody as well, but a gastric erosion may not cause vomiting. Blood may be black because it will be partially digested. Loss of blood may cause one to develop anemia . Risks Anemia and other problems related to blood loss may occur. Sometimes a person with a gastric erosion will experience severe bleeding all at once here red bloody vomiting may occur, and or black bowel movements. Treatment Doctors can prescribe alternative anti arthritic drugs, and alternatives for aspirin are available. Once you have gastric erosion, however, you cannot treat it without the aid of a physician. To keep from getting gastric erosion, drugs that could irritate your stomach should be taken with or directly after food. Avoid alcohol. Those with severe gastric erosion will likely be hospitalized and given a blood transfusion .

There are dozens of erosion prediction mathematical model models . Most have been developed for agricultural areas and are design to compare predicted annual rates of soil loss from broad areas under various cropland and rangeland management techniques. Some are purely Statistics statistical models, others mechanistic. Two of the more widely used methods in North America are the Universal Soil Loss Equation Revised Universal Soil Loss Equation RUSLE and WEPP Water Erosion Prediction Project erosion model WEPP . Much of the research on erosion rates is directed towards supporting or fitting these competing models. In particular much of the mining mineland erosion literature is solely focused on fitting or improving RUSLE parameters. Aside from a few new deterministic gully erosion models, these models do not consider gully erosion mostly due to difficulties in modelling, and partly because gullies are often repaired in agricultural, forestry, or mining environments.

Slump Material slips down along a curved surface When the slope becomes too steep, the base material cannot support the rock and sediment above. Water can cause slump by slipping weakening the slipping mass. Where a stronger layer rests on top of a weaker layer, it collapses. A curved scar is left where the slumped materials originally rested. Creep Materials slowly shift downhill Creep is caused by gravity alone This process is extremely slow and would be difficult to see without a LOT of time and measurements Gravitational erosion can leave major scars and land.

Bank erosion is the wearing away of the banks of a stream or river . This is distinguished from erosion of the bed of the watercourse, which is referred to as scour . The root s of tree s growing by a stream are undercut by such erosion. As the roots bind the soil tightly, they form abutments which jut out over the water.

The interplay between erosion and tectonics has been a matter of debate since the early 1990s. While Tectonics tectonic effects on surface processes such as erosion for example, the river entrainment subsequent to a tectonic rock uplift have been long recognized, the reverse the effects of erosion on tectonic deformation has only recently been addressed thanks to the availability of computer modelling techniques. ref Willett, Sean D., et al., Tectonics, Climate and Landscape Evolution , Geological Society of America Special Paper 398, 2006 ISBN 0 8137 2398 1 http earth.geology.yale.edu brandon Eprints Willett 20etal2006GSASP390 Introduction.pdf PDF of Introduction ref Tectonics modify erosion because it modifies the surface topography , which is the most important parameter controlling surface processes of mass transport. Erosion might be reduced on a flat landscape before a normal fault generates a topographic gradient for example. Landforms are generally considered as the result of the interaction between the tectonic and isostatic uplift and the response of surface erosion. The way the tectonic deformation is influenced by erosion is more subtle and is produced by the weight of the mass removed eroded from the surface and the weight of the deposited sediments, which in some circumstances can become relevant enough as to modify the state of stress at depth and the pattern of tectonic deformation. Although originally proposed for continental collision settings, presently the effects of erosion on tectonic deformation have been extended to a diversity of tectonic settings including continental margin s, plate subduction , and high plateau s.

The cycle of erosion was a model for stream erosion and landscape development proposed by William Morris Davis in the late 19th century. Davis Stages in the fluvial cycle of erosion published in 1909 defined a young, mature, and old sequence in the development of river valleys and the landscape the rivers were eroding. His basic concept includes a rapid tectonic uplift, followed by cessation of the land, which allows the rivers and streams to reduce the surface to a level close to sea level. The concept of peneplain peneplanation was a part of his model. In his model Davies picked up ideas of John Wesley Powell about limitation of erosion on land and concluded that sea level is the ultimate base level for sub aerial erosion. Further he suggested that streams always have at least some gradient and temporary base levels, such as inland lakes, are controlling points upstream of them. The model developed by Davis, though important in historical context, is currently considered only a first approximation . Developments in the sciences of geology and geomorphology , especially the plate tectonics revolution of the 1960s and 70s, have confirmed the preliminary nature of the model.
