There are several ways to prevent erosion, including grassing waterways, conserving tillage, covering crops, managing pastures and fortifying stream and riverbanks. Some erosion control methods, such as fortifying embankments along waterways, take place at the source, while others, such as modifying farming techniques, occur offsite. These techniques help to control and stabilize erosion on short- and long-term bases and are ideally used in combination.Continue Reading
One common method of controlling erosion involves placing filter strips and buffers along river corridors and slopes. These strips help to slow water speed, trap sediment and debris and filter harmful toxins and pollutants, such as chemicals and pesticides. These strips prevent sediment from leaving farm areas and infiltrating nearby water systems. Grassing waterways is another erosion control mechanism that reduces the volume of tillage and reduces soil loss.
Contour farming is a long-term method of erosion prevention that creates perpendicular rows along valleys and crop fields instead of perpendicular rows that run vertically up and down slopes. These crop rows create series of small dams that slow water flow and reduce soil loss. Pasture management is another long-term technique that involves appropriately balancing the number of grazing animals with the size of farm land, which allows water-absorbing vegetation to grow and prevents plants from being uprooted, which in turn reserves critical cover.Learn more about Erosion & Weathering
Lateral erosion is one of the three different ways that rivers and streams erode their banks and beds. As the term implies, lateral erosion is the erosion that occurs on the sides, or floodplains, of a river or stream, and it is also referred to as bank erosion. The other two forms of erosion are headward erosion and downcutting erosion.Full Answer >
Soil erosion solutions include increasing ground cover, mulching, preventing tillage and building structures. The type of solution depends on the area in which the erosion occurs.Full Answer >
Acid rain causes erosion by chemically reacting with certain minerals in rock, causing it to dissolve in the water and otherwise escape the structures in which it is bonded. This is a particularly a problem with limestone and rocks derived from it, such as marble. The basic constituent of limestone is calcium carbonate, which is very vulnerable to acidic compounds.Full Answer >
The difference between erosion and weathering is that erosion involves movement while weathering takes place without movement. Both processes are involved in the decomposition of rocks.Full Answer >
