Soil stabilization is an essential part of road construction and maintenance. It is necessary that soil stabilization is performed to eliminate the risk of environmental concerns. Although all roads need to be repaired and construction increases the economy they can both harm the environment.
Unprotected natural or built earthen slopes are a significant point source erosion problem that can result in dangerous debris flows to lower catchment sites, pollution of rivers and streams, water quality decrease, slope failure and slippage that often result in landslides, economic damage to property, and loss of life.
In forests, the soil surface is usually protected by a layer of mulch from decaying vegetation as well as a kind of surface growing plants. If the soil is exposed under the tree sunshade from overgrazing, vehicles or pedestrians, soil erosion will still occur.
Luckily there's a lot of ways to control erosion
1. Using trees to control erosion
Trees are often considered to be the common answer to control soil erosion. As the roots of a tree help block landslides on abrupt slopes but they don’t stop erosion on moderate hillslopes.
2. Vetiver is technically a grass, but it behaves like very fast growing plants or trees when used in land stabilization techniques. The roots of vetiver are stronger and more secure than the roots of trees. Vetiver has a broad and massive root system which ties to the soil and is very difficult to remove it. The deep and finely structured root system of the vetiver can extend downwards to a height of two to three meters. This is the reason why vetiver is tolerant of dehydration.
Lastly, the modern way to prevent erosion is:
3. Slope stabilization is the resistance of an inclined surface due to failure by sliding or collapsing. Slope stability analysis is based on extensive investigation of the static and dynamic stability of slopes of earthen material, banks, excavated slopes and natural slopes in soil and shale. Slope stabilization and remediation measures may be achieved by different earth retention systems, including soil nailing, soldier pile and lag, sheet piling and secant/ tangent and tieback walls.
Both of these processes can stop erosion, therefore there has to be a way to control the damage to the environment. Soil stabilization not only defends against road maintenance and building but also against many other things.
