Stream erosion: This type is the most erosive. Over time, streams tend to widen and deepen as they remove soil and rock from the area. As erosion by water is happening, the water is carrying what is called the load. The load is nothing more than the sediment Se hela listan på reference.com Erosion control is the exercise of preventing water or wind erosion in the land, construction, coastal areas, and agricultural areas. Below are 15 wonderful methods that you can use to get you started. This flow of water will make the surface of the soil carried away, so this will certainly move little by little the surface of the land. Water that causes a lot of erosion is river water.

The annual direct cost of water erosion to dryland farming in Western Australia is estimated to be around $10.1 million. Water erosion is usually associated with intense rainfall events combined with inappropriate tillage practice, poor ground surface cover, steep slopes and a lack of surface water flow-control Water scouring experiments were carried out to monitor vegetation community succession and its effects on erosion. These results indicate that the sum of plant importance values increased from 260.72 to 283.06, species density increased from 2.5 to 4.5 per m 2 , and the amount of litter and humus increased from 24.50 to 605.00 g/m 2 during the 1 to 40 years of vegetation community succession. 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 Water Erosion. Water erosion is very simplistically speaking caused by rainfall, river flow, waves (wave action, hydraulic action and abrasion), corrosion, glacier movement, thawing, etc., while wind erosion is caused by wind picking up loose particles (deflation) that batter the ground as they fly by (abrasion), causing additional particles to become loose and fly away.
