Soil Bioengineering: Challenges for Planning and Engineering

Abstract

Soil bioengineering is a streambank stabilization method that uses living plants as the primary structural component. It is a promising technique for restoring urban streams, but many challenges remain. This article investigates the causes and consequences of streambank degradation and evaluates the effectiveness of soil bioengineering for erosion control and slope stabilization. Three soil bioengineering projects located on metropolitan Atlanta's waterways (Nancy Creek, Chattahoochee River, and South Peachtree Creek) are analyzed. The research included both primary and secondary data collection activities, involving site visits, documentary review, in-person interviews, photographic documentation, and project monitoring. Five key challenges are revealed: lack of baseline data, short-term vulnerability of installations, inadequacy of previously applied erosion controls, limited site access, and need for community participation. Recommendations include the integration of soil bioengineering strategies within watershed management and urban development plans.
