Error and Domain of Applicability Studies for the Schmugge's Dielectric Model of Moist Soils

Résumé

| In this paper, there was studied correlation of dielectric predictions for moist soils with the measured values, regarding the well known empirical dielectric model proposed by J. R. Wang and T. J. Schmugge. The analysis is based on the measured dielectric data borrowed from the Technical Report EL-95-34, by J. O. Curtis et al., in which the assemblage of soils measured included all of grain-size distributions that are observed in nature, with measurements being performed over the frequency range from 45MHz to 26.5 GHz at the moistures spanning from the nearly dry samples to the ones saturated close to the ¯eld capacity values. As far as it concerns the dielectric constant, the Schmugge model was shown to be applicable in the frequency range from 0.3 to 14 GHz to the soils beyond the ensemble of soils with dielectric data of which it was developed. In the case of loss factor, this model was found to provide for accurate dielectric predictions only over the frequency range from 5.0 GHz to 14 GHz, concerning the ensemble of dielectric data independently measured.
