River Processes The final type of erosion is attrition. Attrition is a way of eroding the river’s load, not the bed and banks. Attrition is where pieces of rock in the river’s load knock together, breaking chunks of rock off of one another and gradually rounding and shrinking the load.

Language attrition Language attrition is related to multilingualism and language acquisition. Many factors are at play in learning (acquisition) and unlearning (loss) the first and second languages. This can be a simple reversal of learning.

What is erosion caused by rivers? Erosion caused by rivers is known as Fluvial erosion. This consists of four main means of wearing down... Hydraulic action: The action of the water. In some cases this is the forcing of air bubbles into cracks in the rock. Abrasion: Material carried by the river (load) collides with or rubs against the bed and banks of the river. Attrition: Fragments within the river collide with each other.

Stream and river When the flow of water in a stream becomes too high to be accommodated in the stream's channel, the water flows over the stream's banks and floods the surrounding land. As it does so, the water immediately slows down and drops its sediment load.

What Is the Definition of Natural Attrition? Natural attrition refers to the natural reduction of a business's workforce due to employees leaving on their own accord. Examples of natural attrition include retirement, relocation or leaving the company to pursue other opportunities at another company or in another industry. Continue Reading.

- Figure 1 Erosion and deposition occur at a bend, or meander, in this Alaskan river. Deltas A river’s current slows when a river empties into a large body of water, such as a lake or an ocean. As its current slows, a river may deposit its load in a fan-shaped pattern called a delta.fter rivers erode rock and soil, they drop, or deposit, their load downstream. Deposition is the process in which material is laid down or dropped. Rock and soil that are deposited by streams are called sediment. Rivers and streams deposit sediment where the speed of the water decreases.

attrition Use attrition in a sentence. If your company has high attrition, you will be forced to continuously advertise, interview and hire new employees to take the place of those employees who have left. Due to the large number of changes the new management was making in the company, the attrition rate among employees skyrocketed. This was a battle of attrition, he tried and tried and still he held out against all of his desire not to.

Understanding the Price of Platinum Jewelry But this formula will give you an idea of the base price of your platinum jewelry. For example, a ring weighing 20.0 grams of platinum may cost $1,425.00. If you divide 1,425 / 20 — you will get $71.25 per gram. That is the amount you are paying per 1 gram of platinum in your ring (inclusive of labor, retail markup, etc.).

- WASTING: SLUMP. In the Fargo-Moorhead region, three types of mass wasting impact slopes bordering the Red River and its tributaries. Two of these, creep and earthflow, generally induce low levels of property damage. Slump, in contrast, can result in major and rapid slope retreat. Slump is common where clay-rich materials are exposed along a steep slope. Such oversteepend slopes naturally occur on the outside of meanders along the Red River.

- Research: Attrition is a reduction or decrease in numbers, size, or strength. A gradual reduction in work force without firing of personnel, as when workers resign or retire and are not replaced (attrition. (n.d). Information Technology companies are notorious for having higher attrition rates.

What are the 4 types of erosion? Rivers erode in four ways: Abrasion or corrasion-This is when large pieces of bedload material wear away the river banks and bed. Attrition-This is when the bed load itself is eroded when sediment particles knock against the bed or each other and break, becoming more rounded and smaller.

Attrition Attrition may be deliberate; that is, if a company is downsizing, it may prefer to lose employees through attrition rather than to conduct layoffs. Other times, however, attrition may be a sign of a weak company or organization unable to attract talent. Attrition is also called natural wastage.

- Overall, generalist attrition was down by 23 percent in fiscal year 2009, compared with 2008. 15) They surmised that the absence of a UPT-like environment for flight training and discipline could be the cause of increased rates of voluntary attrition at UPT.

Attrition ATTRITION. Maggie Sumner. The ‘wearing away’ or progressive loss of data in research. Attrition occurs when cases are lost from a sample over time or over a series of sequential processes.

River Delta When this mid-channel bar is deposited at the mouth of a river, the flow is routed around it. This results in additional deposition on the upstream end of the mouth-bar, which splits the river into two distributary channels. A good example of the result of this process is the Wax Lake Delta in Louisiana.

Avulsion (river) On average, an avulsion will occur every time the bed of a river channel aggrades enough that the river channel is superelevated above the floodplain by one channel-depth. In this situation, enough hydraulic head is available that any breach of the natural levees will result in an avulsion.

Attrition Definition - What does Attrition mean? Attrition is a type of erosion that occurs when bed load erodes. It is characterized by wearing of land as well as the removal of dune sediments, rocks and other particles by the action of tidal currents, wave currents, high winds and other factors. In attrition, rocks and other particles are carried downstream throughout river beds. This kind of movement causes these particles to be broken into tinier fragments. This phenomenon can also take place in glaciated regions, where attrition is typically caused by ice movement.

River study - Burbage Brook, River study-Burbage Brook, Extracts from this document... Introduction. Plateau The plateau is the source of Burbage Brook, which is a fairly large are of high flat land.This is formed by heavy rainfall soaking into the peat, which then filters into the brook...read more. Conclusion. This photograph shows how the lower course of Burbage valley has changed compared to the upper and middle courses. For example it is a lot wider as you can tell and also you can see the floodplain which has formed, also you can see the alluvium which has been left due to the slow velocity.

River Landforms Potholes form mainly in the upper course of the river, in high altitude where the river channel cuts directly into the bedrock. Potholes are the direct consequence of vertical erosion and processes of abrasion.s has already been described, rejuvenating rivers form as a result of a fall in sea level, either as a result of an increase in ice storage or due to isotatic rise or tectonic shifts. Either way the result is a relative fall of sea level to land. Isostatic rise or rebound is caused by the landmass rising.

- Erosion occurs in meanders and fast flowing parts of the river. Deposition occurs when the flow is too slow to carry the particles so drops the dirt and soil it is carrying.… Deposition also occurs on the inside of a meander, which is why the meander stays the same width, but moves about. 12 people found this useful.nswered by The Community. Making the world better, one answer at a time. deposition occurs at the part of a river where there is no longer enough energy for the water to carry the sediments and they are deposited.

Effects of Water Quality and Habitat on Composition of Fish Communities in the Upper Colorado River Basin Absence of fish at site 10 might be attributed more to low streamflow and associated habitat than to water-quality conditions. The abundance and type of fish species at the Blue River site (site 3), a mining land-use site, were low compared to other sites in the Southern Rocky Mountains province.

- In the Cumberland Pateau Ecoregion, this community occurs on flat or gently-sloping alluvial bars of deeply-entrenched river gorges with no particular aspect, from 243- 460 m (800-1512 ft). This grassland occurs on stony bars composed of imbricated sandstone boulders and cobble embedded in sandy alluvium (Wolfe 2008).

- For example, in the Hadejia-Nguru wetlands in Nigeria, annual flooding of about 3,000 km 2, prior to the building of dams was reduced to less than 1000 km 2 after construction(Hollis et al. 1993). In some circumstances, operational procedures can result in rapid flow fluctuations that occur at non-natural rates.
