On uncertainties propagation in modeling and interpretation of EM data concerning saturated granular media

On uncertainties propagation in modeling and interpretation of EM data concerning saturated granular media. Luigi Sambuelli (DITAG – Politecnico di Torino) SUMMARY____________________________________________________________ In this study I calculate the uncertainties occurring either when from experimental E and EM data one wants to estimate the porosity of a two-phase saturated media; or when from the given properties of a saturated granular media one wants to estimate the E and/or EM parameters (conductivity or permittivity). I analyze some of the most common mixing laws used in geophysics. I pay particular attention to uncertainties achievable in field survey to make the user aware of
