erosion

 [e-ro´zhun]
an eating or gnawing away; a shallow or superficial ulceration; in dentistry, the wasting away or loss of substance of a tooth by a chemical process that does not involve known bacterial action. adj., adj ero´sive.
cervical erosion destruction of the squamous epithelium of the vaginal portion of the cervix, due to irritation and later ulceration.

e·ro·sion

(ē-rō'zhŭn),
1. A wearing away or a state of being worn away, as by friction or pressure. Compare: corrosion.
2. A shallow ulcer; in the stomach and intestine, an ulcer limited to the mucosa, with no penetration of the muscularis mucosa.
3. Chemically induced tooth loss, occurring mainly through acid dissolution. When the cause is unknown, it is referred to as idiopathic erosion. Synonym(s): odontolysis
[L. erosio, fr. erodo, to gnaw away]

erosion

(ĭ-rō′zhən)
n.
The superficial destruction of a surface by friction, pressure, ulceration, or trauma.

erosive (ĭ-rō′sĭv) adj.

erosion

[irō′zhən]
Etymology: L, erodere, to consume
1 the wearing away or gradual destruction of a surface. For example, a mucosal or epidermal surface may erode as a result of inflammation, injury, or other causes, usually marked by the appearance of an ulcer. See also necrosis.
2 the action of acid (low pH) substances dissolving tooth structure. Can be due to habitual sucking on citrus fruits such as lemons, from acidic swimming pool water, or gastroesophageal reflux.

erosion

A wearing away, ulceration. See Apple core erosion, Cervical erosion.

erosion

the wearing away of geological formations such as rock, soil, etc. For example, deafforestation or the removal of hedges causes soil erosion.

erosion (ērō´zhən),

n the chemical or mechanicochemical destruction of tooth substance, the mechanism of which is incompletely known, which leads to the creation of concavities of many shapes at the cementoenamel junction of teeth. The surface of the cavity, unlike dental caries, is hard and smooth.

In Iran, several models have been used for estimating soil erosion in Iran, although these methods have not been developed and calibrated for the condition of this country.
Plants vegetative cover in addition to crop residues reduces soil erosion potential, due to the fact that the vegetation cover protects and leads to slowing down surface runoff movement and enhancing surplus surface water infiltration [18-20].
Investigations of the impact of concentrated road runoff on soil erosion, to be complete and comprehensive, should also consider an estimation of the amount of soil loss rather than simply focussing only on the contributing factors.

However, the potential soil erosion corresponding to any combination of slope, top width of flow, and furrow length is still vague.
Intensive precipitation, steep slopes and erodible soils without adequate protection have led to extensive soil erosion in the area and the consequences are devastating including loss of fertile soil and vegetation [4].
To estimate soil erosion and to develop optimal soil erosion management plans, many erosion models, such as Universal Soil Loss Equation (USLE) [57], Water Erosion Prediction Project (WEPP) [20], Soil and Water Assessment Tool (SWAT) [2], and European Soil Erosion Model (EUROSEM) [36], have been developed and used over the years.
The WEPP model simulates many of the physical processes important in soil erosion, including infiltration, runoff, raindrop and overland-flow detachment of soil particles, sediment transport, deposition, plant growth, and residue decomposition.
The national highway in the area is also facing similar problems due to the turbulent nature of the River Teesta, which has been worsened by the heavy downpours, resulting in landslides and soil erosion.
