Levee stability study through 3D analysis of conductivity distribution

Following floods that led to numerous levee failures, significant geophysical recognitions were implemented to detect potential structural weaknesses.

The recognitions were done with a multi-depth EM and allowed 3D block production. This resulted in surveying the weak zones by highlighting areas with more sand or gravel within the levee.

The acquired profiles with the DualEM device allowed a 3D reconstruction of the levee conductivity. Study undergone by our partner GeoAstier.
