Multi-scale characterization of saltwater intrusion in heterogeneous volcanic aquifers with airborne electromagnetics
Résumé
In heterogeneous coastal environments, extension and geometry of saltwater intrusion are controlled by numerous parameters at different scales. Their analysis requires both local accurate data and extensive coverage. Given the significant electrical conductivity of the saltwater, Airborne ElectroMagnetic (AEM) method is particularly adapted for imaging the contrast between freshwater covering saltwater.
