Alternative Slope Stabilization Techniques: Soil Bioengineering
Cory L. Horton, P.E.
This four hour online course provides guidance for the application and design of the alternative slope stabilization techniques of Soil Bioengineering. This course is intended for practicing engineers, and others, who seek additional alternatives to conventional slope stabilization practices. After completing the course the student will have a greater understanding of when, where, and how to implement soil bioengineering. The course content is based on the Natural Resources Conservation Service Engineering Field Handbook Chapter 18 Soil Bioengineering for Upland Slope Protection and Erosion Reduction (61 pages). This publication introduces the goals, describes the design methodology, teaches about construction methods, and provides information to select and implement soil bioengineering for slope stabilization.
This course includes
a multiple-choice quiz at the end, which is designed to enhance the understanding
of the course materials.
At the conclusion of this course, the student will:
Soil Bioengineering is an integrated design technique that combines living biological elements and engineering design methods to protect slopes and reduce erosion. Conventional engineered structures can be costly, difficult to construct, and may not fit in with site aesthetics. Integrating living plant material with slope stabilization can improve aesthetics, decrease construction costs, decrease maintenance, and result in a structure that actually increases in strength over time.
The purpose of this course is to provide guidance on the design and construction of soil bioengineering. You will be directed to the U.S. Department of Agriculture Natural Resources Conservation Service website to study Soil Bioengineering for Upland Slope Protection and Erosion Reduction (1992 edition, 3.5MB 61 pages, PDF file format), which presents the methodology and design approach of soil bioengineering for upland slope protection.
The following contains the outline of Soil Bioengineering for Upland Slope Protection and Erosion Reduction:
650.1801 Characteristics of soil bioengineering systems
650.1802 Basic principles and design considerations
650.1803 Construction techniques and materials
can be a cost effective means of stabilizing slopes with less disturbance than
conventional engineered structures. The vegetated components grow stronger with
time and integrate aesthetically into the natural landscape. Soil bioengineering
is often a viable alternative in sites with difficult access constraints where
the use of equipment is not practical.
