David V. Fitterman 1989 <p><span>A question usually asked during the planning of a transient sounding survey is, "Can information useful to solving the geologic problem at hand be obtained from the measurements?" This question is usually answered by constructing a geologic model for the survey area based upon the best available information to determine which model parameters can be resolved. Specifically, this determination can be accomplished by computing a forward model, varying a parameter of interest, and observing whether the responses of the original and perturbed models are different. Alternatively, inversion-based methods can be used to estimate parameter resolution (Inman, 1975; Glenn and Ward, 1976).</span></p> application/pdf 10.1190/1.1442570 en Society of Exploration Geophysicists Short note; Detectability levels for central induction transient soundings article
