Study of necroleachate migration in saturated and unsaturated zone through geophysical methods.

The objective of this study is to is monitor the degradation of the body of a pig using Electric Imaging and GPR in an area with water table near the surface by detecting variations in conductivity in the soil and the saturated zone during two hydrological cycles. The experiment took place in a private area in the city of Aveiro, Portugal. Multi electrode cables were built by the project team and installed vertically in the area for electrical imaging and also GPR surveys in regular mesh were taken. The preliminary results indicate a important decrease of conductivity even with the influence of rain. Problems with the equipment indicate that a new experiment must be repeated in Brazil, with more control on the area access.
