“…Well log data from 14 boreholes outside RSU but in the same sedimentary basin were used to obtain statistical parameters for porosity such as stratum thickness, vertical mean length and volumetric proportion (Table 1). Spatial random fields of porosity in four geological formations above were generated by transition probability based geostatiscal simulations (Carle and Foggs, 1996;Dai et al, 2004;Ye and Khaleel, 2008). Once spatial distributions of porosity in these rocks had been acquired, permeability spatial distributions were obtained on the basis of empirical correlation between porosity and permeability.…”

“…Assuming that both covariance function and transition probability are exponential (Dai et al, 2007), and that the cross-covariances are negligible (Lu and Zhang, 2002;Dai et al, 2004), the composite covariance function for porosity is expressed as (Dai et al, , 2007:…”

“…Numerous studies have applied hierarchical modeling frameworks to model aquifer materials (e.g., Scheibe and Freyberg 1995;Weissmann and Fogg 1999;Barrash and Clemo 2002;Dai et al 2004;Ritzi et al 2004) using a variety of modeling approaches (Koltermann and Gorelick 1996). Object-based (or morphological) modeling approaches, which focus on the characteristic geometries of a sedimentary deposit, have been used in many hydrogeological studies (e.g., Jussel et al 1994;Scheibe and Freyberg 1995;Miller et al 2000).…”
