Un-Complicating the Stabilization Selection Process – Part II

This webinar aired on December 13th at 12pm CST.


The first part of this webinar discussed the functions of a Turf Reinforcement Mat (TRM), the importance of hydraulic testing, and the critical need to validate TRM performance in various hydraulic scenarios prior to use. The second part of this webinar will focus on the remaining considerations for designing with TRMs, such as appropriate applications, material durability requirements, proper installation and maintenance, and erosion and superficial slope stability analyses.

Objectives of Webinar:

  • To recognize what applications are appropriate for the use of TRMs
  • To gain an understanding of the need for strength and durability of TRMs
  • To become familiar with the proper site preparation and installation procedures for TRMs
  • To learn how to properly analyze the erosion potential within an open channel
  • To understand the need for geotechnical evaluation of surficial slope stability on steepened slopes



View Part I


1. Which of the following applications below are appropriate for the use of a TRMs, HPTRMs, or EEAS?
2. Which material has proven to deter animal burrowing and prevent wildlife entrapment?
3. Securing pins are required to be installed at TRM overlaps, within the trenches, and across the TRM panels.
4. When designing with TRMs, which of the following should be evaluated?
5. Which of the following can be used to stabilize against surficial slope failures?
6. The durability of a TRM/HPTRM is dependent on which of the following?
7. TRMs, HPTRMs, and EEAS cannot be used in conjunction with other hard armoring solutions.
8. Which material has proven to resist Non-Hydraulic Stresses such as maintenance and debris loading?
9. Trenches are required around the perimeter of the TRM installation in order to key in the material and prevent undermining of the installation.
10. Which methods can be used to establish vegetation with TRMs, HPTRMs, and EEAS?
