INSTRUCTOR: Robert M. Koerner, Ph.D., P.E., D.GE, Dist.M.ASCE
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.
