Urbana Campus Research Calendar (OVCRI)

In this 100th FGI webinar, Dr. J.P. Giroud will describe new developments in geomembrane liner design and performance. This presentation will address essential aspects of 10 subjects: (1) Time necessary for a soil layer on a geomembrane liner system on a slope to slide when it is subjected to a rainfall. (2) Impact of seepage forces on slope stability. (3) Sliding of trucks and dozers on geomembrane liner systems. (4) Creep of seams of bituminous geomembranes. (5) Effect of temperature on the mechanical properties of geomembranes. (6) Frequency of holes in geomembrane liners. (7) Rate of leakage through holes in vertical geomembrane liners. (8) Magnitude of water diffusion through geomembrane liners. (9) Intentional geomembrane wrinkles. (10) Geomembrane seams next to rigid structures. All cases will be illustrated by field examples, and, in all cases, relevant papers will be mentioned. 1.0 PDH
