Abstract

Hydrogeological applications require the characterization of subsurface properties, in particular for predicting contaminant transport. The lack of field data implies definition of a wide prior, which, when combined with computationally expensive transport simulations, becomes prohibitive. To improve computational efficiency, we propose to reduce the prior by quantitatively comparing field and simulated geophysical images. The comparison relies on the computation of several distances based on wavelet decomposition, multiple-point histograms, or the pattern connectivity of images. Our method is illustrated with field ground-penetrating radar sections acquired on an active braided river bed. It allows us to select and reject some conceptual models of the geology and some parameter combinations.
