Abstract
P042 DEVELOPMENT OF A 3D GEOELECTRICAL MONITORING SYSTEM TO FOLLOW HYDRIC BEHAVIOR OF SOILS DURING RAINFALLS Abstract 1 During recent years the DC geoelectric method has been widely used to investigate the structure of the subsurface. However so far the DC geoelectric method was hardly used to detect saturation changes with time. Few applications are known where this method was used as a permanent 3D monitoring system to follow the soil moisture content during rainfall or irrigation (Michot and al. 2001; Benderitter and Schott 1997). The 3D electrical measurements repeated in time and in particular during rainfall will make it
