The report describes a study conducted to verify the lateral drainage component of the Hydrologic Evaluation of Landfill Performance (HELP) computer model using laboratory drainage data from two large-scale physical models of landfill liner/drainage systems. Drainage tests were run to examine the effects that drainage length, slope, hydraulic conductivity and depth of saturation have on the lateral drainage rate. The drainage results were compared with HELP model predictions and numerical solutions of the Boussinesq equation for unsteady, unconfined flow through porous media.
