Bio engineering is the mixture of principles of biology and tools of engineering. Bio engineering is cost effective use of vegetation required for slope stabilization and control run off and their effects on erosion of soil and transportation. It is locally adapted method to control landslides and loosening of soil. Bio engineering plays a key role where civil engineering fails and answers to common slope stability problems to road construction and negative impact of road construction. Proper roadside drainage need to be provided to divert heavy run-off are some of the examples required in bio engineering for safer place.
In general, bio engineering is the attempt to regulate and modify bio-system so as to control natural biological systems. These are extensively used for stream corridor stabilization and erosion control, slope stabilization of hills and along roads and highways especially along hillsides.
