Answer 1

HEY MY FRIEND U R ANSWER IS HERE

______________________________


The simplest and most natural way to prevent erosion is through afforestation i.e. planting eco-friendly vegetation. Plants establish root systems, which stabilizes soil and prevents soil erosion against weathering forces.

Using geosynthetics like erosion control mat is an effective method because it holds the root of vegetation and also stabilizes soil. When used in conjunction with growing vegetation, it is even more effective. There are three main types of erosion control mat: polymeric 3-D mat, jute mat and coir mat.

Applying a layer of mulch/fertilizer to the soil top allows the soil to slowly soak up water, as it protects against rain impact, and restores pH levels and allows vegetation to grow and thus helping with erosion prevention.
