Part 2: Controlling uplifting gas bubbles in exposed geomembrane-lined ponds
February 1st, 2018
Part 1 of this series in the October/November 2017 issue of Geosynthetics demonstrated how the size, shape, pressure, and stresses and strains experienced by geomembrane bubbles surrounded by a confining fluid could be analytically estimated. Two different field case histories exhibiting the extremes of bubble sizes in ponds lined with 60-mil (1.5-mm) high-density polyethylene (HDPE) […]
Part 1: Controlling uplifting gas bubbles in exposed geomembrane-lined ponds
October 1st, 2017
There is a substantial legacy of literature devoted to the design, construction and operation of geomembrane-lined ponds, with perhaps the best and most complete reference being 34 years old by Giroud (1983). Even with this long history, there continue to be problems and failures with lined ponds. One of the problems continuing to plague the […]

Dear Editor, Kudos to Rick Thiel, Ed Kavazanjian and Xuan Wu on their excellent article, “Design considerations for slip interfaces on steep-wall liner systems” (February/March, 2015). My consulting practice is principally heap leaching and most of my work now is reviewing designs for complex systems, and troubleshooting when things don’t work out as planned. The […]
