Soil Bioengineering

Anchored plantings along stream banks serve as the basis for this technique. Soil bioengineering and biotechnical engineering are cost-effective and environmentally compatible ways to protect slopes against surficial erosion and shallow mass movement. These approaches provide alternatives to structural channel "improvements." They raise questions about the notion of why engineers ever considered that concrete-lined channels should be considered "improved" (Gray and Sotir, 1996). Generally, bioengineering solutions must also include a strategy to carry floodwaters away.

The bioengineering technique is gaining support throughout the United States and Europe. It is less expensive to install and less expensive to maintain as well. The broader adoption of soil bioengineering may radically alter floodplain management.
