Joint Inversion of Phase Velocity and Apparent Resistivity using Genetic Algorithms: A Synthetic Model

Emily Mudge

Independent inversions of apparent resistivity or phase velocity have assisted in obtaining global subsurface physical parameters such as resistivity and S-wave velocity. Restrictions on the attainability of actual observations, makes the inversion of observation data to a true model difficult. A joint inversion of Rayleigh wave phase velocities and apparent resistivity is proposed using genetic algorithms, in order to obtain appropriate model parameters from insufficient data in shallow geophysical exploration. The inversion of synthetic data supported the effectiveness of the method.
