Innovation and Challenges for Soil bioengineering in a Changing World
International audience Riverbanks are assuming a large number of important ecological functions: biodiversity support, resistance to invasion, ecological corridors, biomass production, water purification, temperature regulation, flood control, and recreation. Besides hard engineering, soil bioengine...

International audience Riverbanks are assuming a large number of important ecological functions: biodiversity support, resistance to invasion, ecological corridors, biomass production, water purification, temperature regulation, flood control, and recreation.

First thought of mimicking nature to fulfil the function of erosion control, soil bioengineering techniques are now also formed to assume some of the other important ecological functions of riverbanks.
