N2 - In this work optimum protocols using the criterion of Jacobian matrix were tested to increase the resolvable power of surface-to-tunnel electrical resistivity tomography measurements. The problem was approached through synthetic numerical modeling, experimental data collected in a controlled tank environment that was constructed for this purpose and data that were retrieved from a real case scenario in Crete, where an aqueduct tunnel exists in the archaeological site of Eleftherna. The resistivity inversion images were reconstructed through a 2-D inversion algorithm that was modified to account for the special surface-to-tunnel ERT measurements. The optimized data sets contained fewer measurements with respect to the original data sets (∼30%) but the optimized inversion images show comparable resolvable capabilities with the original inversion models.
