This webinar was co-sponsored by ASCE's Geo-Institute (G-I) and ASCE Continuing Education
Instructor: Robert M. Koerner, Ph.D., P.E., BC.GE, Dist. M.ASCE
Course Length: 1.5 Hours
Purpose and Background
Geosynthetics have made a major impact regarding erosion control and revegetation of soil slopes. Whether temporary or permanent time frames, these easy-to-use rolled products come in many types and varieties. This webinar properly characterizes the materials and then provides designs for their use on both soil slopes and in channel/ditches. This webinar also presents laboratory bench-scale and full-scale field test methods. It also explains those methods. This webinar discusses a new generic turf reinforcement mat (TRM) specification, along with the required test methods which are necessary for use by designers and specifiers. The webinar concludes with a summary and recommendation section.
Primary Discussion Topics
- Basic soil erosion mechanisms
- Erosion control product categories and examples
- Design methods for soil slopes and channel/ditches
- Large scale laboratory tests
- Full scale field test sites
- Generic specification for turf reinforcement mats
- Summary and recommendation
Learning Outcomes
Upon completion of this course, you will be able to:
- Identify the basic mechanisms of soil erosion
- Describe the plethora of available products and characterize them into groups
- Design methods for use on soil slopes and in channels/ditches
- Illustrate large scale laboratory test methods
- Illustrate full scale field test sites
- Present a new generic specification for turf reinforcement mats

Webinar Benefits
- Provide participants with the full array of rolled erosion and revegetation products that are available and categorize them accordingly
- Illustrate numeric examples of design when used on slopes and in channels/ditches
- Learn how to test in three modes: large-scale lab, full-scale field, and ASTM tests for use in a new generic specification

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion
To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
