The Next GSI Webinar from the Geosynthetic Institute will focus on “Geosynthetics in Erosion Control.” This high-quality professional development opportunity will be held on 13 September 2017 from 11:30 am – 1:00 pm (EDT). One of the major topics within this is the relationship between erosion and landslides.

  • GSI Members – USD $200
  • Non GSI Members – $250

GSI Director Emeritus Dr. Robert Koerner has provided the following synopsis of the “Geosynthetics in Erosion Control” webinar:
The estimated society cost of landslides in the U.S. is estimated at $2 – 5 billion, and worldwide might even approach $10 billion.  The percentage triggered by surface erosion is certainly a major contributor.  While the mechanisms of soil erosion is well-known (consisting of detachment, transportation and deposition) its control is largely empirical.  This webinar will present the various approaches using;

  • Temporary biodegradables (natural materials)
  • Long-term polymeric (geosynthetics)
  • Hard armor systems (stone, concrete, etc.)

Full-scale field tests in Cincinnati will substantiate the positive influence of turf reinforcement mats and product testing including ASTM (small scale), TRI (large scale), and field test sites will be illustrated.
Two design approaches will be shown with numeric examples.  They are the Universal Soil Loss Equation (USLE) method for slopes, and velocity/shear stress methods for channels and ditches.  They will be critiqued accordingly.
A summary of the webinar and recommendations will be offered, including an appeal for instrumented field monitoring research and subsequent analytic modeling.
