embankments to protect soil
Answers
Answer:
Natural way
The most effective, natural way to control soil erosion on steep slopes and embankments is to plant vegetation. Not only will the grass, fescue and leaves help to slow down raindrops as they fall, the roots of the plants will also help to hold the soil together, making it harder for water to wash it away.
Explanation:
Artificial way
Other than planting vegetation, there are also a variety of artificial solutions you can use. For instance, the use of geomats has become popular over the last few years. Geomats are water permeable polymers that are used to help fix soil elements, grass and small plant roots, and have been shown to work extremely well, especially on barren slopes that have no vegetation. There are even biodegradable geomats that are now being produced that are designed to prevent erosion and give freshly planted vegetation a chance to grow.
