Interactive comment on “Stratigraphic Identification with Airborne Electromagnetic Methods at the Hanford Site, Washington” by Piyooh Jaysaval et al

The paper presents a 3D forward modeling inserted in 2D inversion schemes of an Airbone electromagnetic (AEM) data set. The data set is consequent and the computation is performed thanks to an extensive parallelization of the code. The results of the inversion are compared with a geologic framework model (GFM) built from boreholes data. AEM images show divergences with the GFM where it is more uncertain due to a lack of borehole. The resistivity images presented here are a good proxy to delineate the interfaces between the different geological units of the studied area. Some geological units being more transmissive than others, the knowledge of their respective pattern is necessary to estimate the transport of the contaminants that have been discharged on the studied site.
