About Lesson
Bio-engineering:
- Integrated technology that uses sound engineering practices in conjunction with ecological principles to:
- a) design & construct vegetative living systems to prevent erosion,
- b) stabilize shallow areas of soil instability,
- c) protect and enhance a healthy system.
- Uses live plant materials and flexible engineering techniques to eliminate environmental problems.
- Different combinations of methods can be used on cut-and-fill slopes along roadways, landfill covers, and stream banks.
- In areas of existing or potential mass wasting, it may be best to use a bio-engineered system alone or in combination with soil bioengineering.
- Construction of engineering structures is expensive, and a relatively cheap option so in our cases there is a need for alternative conservation methods that can be adopted with less expenditure, use locally available materials, and are environmentally friendly.
- To control the surface erosion on the fill slope, a napier was grown in the Shivapuri Watershed Road erosion control program.
- Many landslides-affected areas like Krishna Bhir are rehabilitated by the use of bioengineering measures.
Advantages:
1) low cost and lower llong-termmaintenance cost.
2) low maintenance of live plants after establishment.
3) environmental benefit of wildlife habitat.
4) water quality improvement.
5) compatibility with environmentally sensitive sites.
