Design of exposed geomembrane-lined ponds

摘要

Part 1 of this series (Thiel 2017) demonstrated how the size, shape, pressure, and stresses and strains experienced by geomembrane bubbles inflated with gas could be analytically estimated. Part 2 of this series (Thiel 2018) evaluated the considerations for incorporating a gas-venting underdrain below the geomembrane liner. The current, and final, Part 3 of this series provides engineering and operational solutions to induce lateral movement of the bubbles to upstream side slopes, where they can be vented.
