Integrated GPR and Geo-Resistivity Study of Shallow Stratigraphy in Sandy Coastal Environments

A025 INTEGRATED GPR AND RESISTIVITY STUDY OF SHALLOW STRATIGRAPHY IN SANDY COASTAL ENVIRONMENTS Abstract 1 We performed an integrated Multi-Fold GPR and resistivity survey in a coastal area in the northern part of Italy (Adriatic coast) to reconstruct 3D stratigraphy to localize vadose zone and water table and to identify possible man-made structures and excavations. The spatial sampling was sufficiently dense to perform 3-D interpretation of radar data and 2.5-D reconstruction of iso-resistivity surfaces across the grid. Processing of GPR Single and Multi Fold data focused on true amplitude signal recovery in order to preserve information related to electromagnetic impedance
