Abstract. We present geophysical and remote sensing measurements on a flood dike, in the framework of the Polder2C’s Interreg European Project (https://polder2cs.eu/). Electrical Resistivity Tomography (ERT) and Ground Penetrating Radar (GPR) profiles have been performed alongside and across the dike. The geophysical measurements are then combined with a Digital Terrain Model (DTM) caarried out with a RGB visible camera on board an Unmanned Aerial Vehicle (UAV). Integrated 3D results enrich data interpretation and form the basis for Polder2C’s future experiments.
