The Appropriate Use of Engineered Earth Solutions


Course Information

Multiple technologies are available for stabilizing and protecting steepened slopes, banks, and levees. Engineered Earth Solutions are innovative technologies that use geosynthetic materials and natural vegetation to reinforce earthen structures, providing increased geotechnical stability and reduced erosion. It is important to understand the different design requirements and geometric limitations of these technologies in order to optimize the solution for your project. What is the most efficient solution for the project? How steep of a slope can be built or protected with these systems? How does normal water level in a channel affect the overall design? Can the in-situ soil be re-used on the project?

This article presents design information for the use of solutions such as Engineered Earth Armoring Solutions® (EEAS), Engineered Wrap-Faced Vegetated Solutions (EWVS), and Engineered Bank Stabilization (EBS) when considering the following:

• Which hydraulic and environmental conditions need to be evaluated?

• How can the systems be modeled from a geotechnical perspective?

• What are the critical aspects of overall geometry and constructability?
