Water is one of the main culprits of erosion. Falling water makes a small indention in the soil, which sends small particles of dirt a long distance, so the faster it rains, the faster the soil will run off. This sends the soil into deep channels. If this water wears away the banks of the river, it is then called bank erosion. However, if the erosion is caused by heating of permafrost, it is called thermal erosion and can occur on coastlines and on rivers, usually in the Siberian and Arctic regions.
The other main cause of this process is wind, which happens in the desert regions where it is easier for dust particles to be picked up and thrown into solid surfaces, thus reshaping those surfaces over time. As these particles roll on the ground, they are lifted and bounce back after sometimes being held in the air a great distance.
There are also several ways that humans contribute. These are the heavy tilling used by many farmers today so that there is nothing to protect the soil from the run off that is caused by heavy rains. Deforestation is another threat, which is when logging companies clear cut an area and remove all trees in a defined area, causing severe run off after heavy rain.
This erosion unfortunately results in the permanent loss of topsoil, which in turn can cause the collapse of the region’s environment and the death of the living organisms in the area. When we observe an area for a long period of time we can figure out the best erosion control products to use in each situation.
A commonly used natural method creating a windbreak to control the amount of wind that an area is subjected to. You could also terrace your field at different levels to control the amount of run off.
To help prevent further sediment depletion, there are several different erosion control products that you can use to keep your land intact. For drain protection, coir wattles and control logs are great options because they are made from biodegradable materials. You can also use bags that you fill with rocks to give your land more support. Another thing you can use to protect the nearby waterways is dewatering bags and geo-textile tubes so that dirt can be filtered before it runs into the water. These options are good for power plants, commercial ponds, and along shorelines.
