“…According to this approach the new measurement is determined using a kriging interpolator at the point with the largest estimation error or at the point that yields the minimum estimation error in the area of interest. FMDs using the geostatistical approach have been presented by De Marsily [1986], Hachich and Vanmarcke [1983], Delhornroe [1978], McBratney et al [1981], Bardossy and Bogardi [1983], Carrera et al [1984], Carrera and Szidarovszky [1985]. The major drawbacks of these methods are (1) the dynamics of the groundwater system are not considered, (2) the economical cost and the benefits of network sampling are not incorporated, and (3) in cases with no prior data the entire area of study is characterized by the same estimation error, and therefore there is no indicator or criterion to determine the first measurement location.…”

“…Variability is an objective, though likely unknown, value that depends upon the geoiogy. Uncertainty and variability can be combined by treating hydraulic conductivity as a random field in a Bayesian framework [Hachich and Vanmarcke, 1983].…”

“…A formulação da análise probabilista tem vantagens devido ao fato de que os erros nas observações e a confiabilidade dos parâmetros estimados podem ser considerados de uma maneira direta, além disso, mediante a visão de atualização bayesiana é possível adicionar novas informações para a estimativa dos parâmetros (Hachich & Vanmarcke, 1983;Ledesma et al, 1989). Ainda quando existe suficiente informação para análises estatísticas, uma estimativa muito mais robusta da variabilidade geotécnica pode ser obtida pela combinação de informações anteriores, usando técnicas de atualização bayesiana (Baecher & Christian, 2003).…”
