Evaluating the Use of Electrical Resistivity Imaging Technique for Improving CH sub(4) and CO sub(2) Emission Rate Estimations in Landfills

Use of electrical resistivity imaging technique for improving methane (CH sub(4)) and carbon dioxide (CO sub(2)) emission rate estimations in landfills is evaluated. The objective is to apply and evaluate the combination of the geo-engineering technology and static chamber technique (SCT) in the main landfill of the island of Crete in the south of Greece. Electrical resistivity tomography (ERT) analyses can be a vital tool in gas emission rate estimations in landfills, regardless of the landfill operation pattern or the existence of information regarding the site prior to waste disposal. Selected characteristics points in the landfill are used for gas emission analysis using SCT. ERT is unable to determine the age and the state of the buried waste, while SCT cannot estimate emissions in places where surface leachate or precipitation block the emission of gases.
