Impact/Purpose:
The objective of this study is to compile the published hydraulic properties of various waste materials that are typically disposed of in landfills but were not included in the model and develop default values of hydraulic properties for these materials that can be used to update the HELP model. The published hydraulic properties data of the materials that are currently included in the HELP model were also compiled.
Description:
The Hydrologic Evaluation of Landfill Performance (HELP) model uses waste-specific properties such as hydraulic conductivity, porosity, wilting point, and field capacity for modeling vertical percolation of leachate through the deposited waste and cover layers to estimate the leachate generation rate and the head on the liner. However, the model includes default values of hydraulic properties of only a limited number of waste materials.
