Inversion results of anomalous bodies under valley topographical model. (a) The relative fitting error RMS during the inversion process; (b) slice of resistivity 3D inversion result; (c) slice of resistivity inversion result at XOZ profile; (d) slice of resistivity inversion result at YOZ profile. The outline of the true model is indicated by the white boxes.
