Question

How can the transportation of soil by the above mentioned agents be reduced?

Answer 1

Transported soils form from weathered material deposits, which are transported by natural forces to a new site, away from the site of origin. The type of transport soil is determined by the agent, such as wind, water, ice or snow, that assists in its transportation. Transportation of soil can be reduced by:

• Vegetation: The simplest and most natural way to prevent erosion is through planting vegetation. Plants establish root systems, which stabilizes soil and prevents soil erosion.soil erosion
  
• Geotextiles: Using geotextiles is an effective method because it also stabilizes soil. When used in conjunction with growing vegetation, it is even more effective. There are three main types of geotextiles: woven, nonwoven, and coir.
  
• Mulch/Fertilizer: Applying a layer of mulch to the soil top allows the soil to slowly soak up water, as it protects against rain impact, and restores pH levels helping with erosion prevention.
  
• Retaining Walls: Retaining walls can be built around the area of erosion to prevent water run off. Runoff water leads to further erosion, and if used with other methods, retaining walls can be a very effective way to prevent soil erosion.
