... provisions that permit an alternative liner design, provided that the alternative liner is equivalent to, or as effective as, the prescriptive liner. The current approach for demonstrating equivalency is based on comparing leakage rates for the alternative and prescriptive liners. This approach is too...

...J.P. Giroud; A. Zhao; R. Bonaparte Design engineers often assume that a geosynthetic liquid collection layer and a granular liquid collection layer having the same hydraulic transmissivity are equivalent. In the United States, such equivalency is often mandated by regulations for leachate...
