Session 3.2 ___ GNGTS 2023 Fig. 2 a) the resistivity model of the ERT crossing the piezometer #1 (the northernmost in Fig. 1, 1 m electrode spacing); b) the GPR result for the piezometer line (400 MHz antenna). The meaning of the black dashed lines is explained in the main text. References Haldorsen, S. and Heim, M.
