摘要: The spectral analysis of the balance equation ground water flow, associated to an asymptotic expansion conductivity (K) and head (h) fields, permits show that high wave number components source terms, F, conductivity, K, are attenuated when h is computed as solution equation. This has important consequences on inverse mapping (h, F) → K: in fact it not possible recover a reliable way because small errors corresponding amplified so they can hidden true signal.
