dc.description.abstractA numerical model is developed to simulate the generation, movement, extraction, and surface emission of landfill gas as well as possible air intrusion in a sanitary landfill equipped with an active or a passive gas collection system. The model was validated using results and data published in literature and has been used to study how the efficiency of a gas collection system may be impacted by a number of factors including vacuum pressure, well screen length, intermediate and final covers' thickness and permeability, number of gas collection wells and direction of well placement. The results suggest that a higher gas collection rate can be achieved by using a vertically placed well with a stronger vacuum pressure, a longer well screen, and a thicker and less permeable final cover, while undesirable air intrusion may be minimized by installing a larger number of wells.
