ABSTRACT
This chapter proposes a temporal imagery of water circulation in a moving mass by Electrical Resistivity Tomography. In most of failure landslide processes fluids are considered as the most important triggered factor. In order to constrain the risk associated to the landslide, it appears necessary to localise and understand the fluids draining network inside the soil mass. The geophysical methods were developed and applied to the study of instabilities of ground. A best knowledge about landslide processes requires the characterisation of the triggered factors and their impact on the process cinematic. These factors are often time dependent and that a reason why it is very complex to have a quantitative approach. In most of failure landslide processes fluids are considered as the most important triggered factor. In order to constrain the risk associated to the landslide, it appears necessary to localise and understand the fluids draining network inside the soil mass.
