It is difficult to accurately predict each flow rate of landfill gas and leachate extracted from many of wells, which have been completed into a waste landfill containing gas and water. However it may be approximately predicted if we can define only relative fluid permeability of gas and leachate flowing through landfill porous media. Therefore numerical simulation using multi-phase flow equations makes use of ei s input data of the relative permeability which is measured and calculated in laboratory environment like in-situ, and consequently we can quantitatively obtain each flow rate of gas and leachate from collection wells. These series of technologies can provide with the important informations to determine the success or failure of landfill gas energy and landfill stabilization. This paper analyses the characteristics of landfill gas collection by six classes of case studies for none described landfill.
