Comparação de resultados de modelagens diretas e investigações elétricas 2D em área de depósito de resíduos urbanos

The use of direct and inverse modeling to planning geophysical investigations to provide the best field parameters. This work compares synthetic and real data electric resistivity 2D results obtained in the area of the antique landfill of Ribeirao Preto, Sao Paulo state. The results confirm the efficiency of the polo-dipole array in the identification of the limits and the ditches base of residues disposition and the find the zone of leachate flow.
