Spectral analysis of the balance equation of ground water hydrology / M. Giudici, C. Vassena. - In: TRANSPORT IN POROUS MEDIA. - ISSN 0169-3913. - 72:2(2008), pp. 171-178.
Abstract:
The spectral analysis of the balance equation of ground water flow, associated to
an asymptotic expansion of the conductivity (K) and head (h) fields, permits to show that
the high wave number components of the source terms, F, and of the conductivity, K, are
attenuated when h is computed as solution to the balance equation. This has important consequences
on the inverse mapping (h, F) → K: in fact it is not possible to recover in a reliable
way the high wave number components of K, because small errors on the corresponding
components of h are amplified so that they can hidden the true signal.
