Utilização de métodos geofísicos elétricos no estudo de célula experimental de aterro sanitário

Geoelectrical methods are essential tools for investigating urban solid waste landfills. In order to identify and characterize the waterproofing infrastructure of the area and the body waste, resistivity and induced polarization were used in an experimental cell set up according to existing principles of engineering landfill, located in Campinas city, State of Sao Paulo and monitored by University of Campinas UNICAMP. The collected data were processed using the software RES2DINV. The results indicate the efficiency of the electrical resistivity method to identify the geometry of the cell and of the structures with resistive and conductive anomalies as well as to interpret the cell dynamic behavior.
