About Lesson

Bio-engineering measures of soil erosion control

  • Jute netting with grass lines plantation, site seedling of shrub and trees, vegetated gabion wall, brush layering, palisades, live check dam and fascines are recommended bio-engineering measures for controlling instabilities and erosion problems along the road.

 

Advantages of bio-engineering method of soil erosion control

  • Low cost and lower long term maintenance cost.
  • Low maintenance of live plants after establishment.
  • Environmental benefit of wildlife habitat.
  • Water quality improvement.
  • Compatibility with environmentally sensitive sites.
