A rock storage pile is being designed for a mine in West Virginia. The pile is lined with reinforced GCL overlain by a 1.5 mm thick HDPE geomembrane. A heavy nonwoven geotextile is placed on top of the geomembrane. Because the rock is porous (K = 10-2cm/s), it is used as the main LCS stone and no additional leachate collection stone is being installed. Specify the base slope required to keep the head below 25 cm if the design storm is 0.8 cm rain/day and the pipe-to-pipe lateral spacing is 60 m Is this rock a reasonable material to replace the LCS stone?
