... prediction procedure, the initial consideration for proper laboratory simulation is obviously important. In the example of a nonexposed 1.5  mm thick HDPE geomembrane, the simulation was of a liner situated under 50 m of solid waste, with 300 mm of liquid head above and atmospheric conditions below...

...K.R. Reddy; R.E. Saichek This paper presents the results of large-scale laboratory simulation tests conducted to evaluate the relative performance of different cover systems, consisting of a granular soil layer (i.e. a drainage layer) both with and without the presence of a needle-punched nonwoven...
