Modeling dispersion in three-dimensional heterogeneous fractured media at Yucca Mountain

The impact of medium architecture of alluvial settings on non-Fickian transport

“…Such competition might persist until the plume covers many integral scales containing both preferential flow paths and immobile zones, so that the fast and slow motions of particles can be counterbalanced. It is well-known that the presence of high-permeability features can significantly enhance plume dispersion [65]. The above analysis shows that the low-permeability features of alluvial settings can also play an important role in plume spreading, because the mass hold-back in floodplain facies enhances the stretching of the plume [55].…”

Expert elicitation of recharge model probabilities for the Death Valley regional flow system

“…The subjective prior model probabilities can be directly obtained through expert elicitation. The expert elicitation has been applied to many studies, for example, future climate change (Arnell et al, 2005;Miklas et al, 1995), performance assessment of proposed nuclear waste repositories (Hora and Jensen, 2005;McKenna et al, 2003;Draper et al, 1999;Hora and von Winterfeldt, 1997;Zio and Apostolakis, 1996;Morgan and Keith, 1995;DeWispelare et al, 1995;Bonano and Apostolakis, 1991;Bonano et al, 1990), estimation of parameter distributions (Parent and Bernier, 2003;Geomatrix Consultants, 1998;O'Hagan, 1998), development of Bayesian network (Pike, 2004;Stiber et al, 1999Stiber et al, , 2004Ghabayen et al, 2006), and interpretation of seismic images (Bond et al, 2007). Formal expert elicitation processes have been proposed by Hora and Iman (1989) and Keeney and von Winterfeldt (1991), among others.…”

Modeling anisotropic flow and heat transport by using mimetic finite differences

“…Modeling anisotropic flow through heterogeneous or fractured porous media is required for subsurface energy production and environmental protection, such as production of hydrocarbons (e.g., Srinivasan and Azom, 2013) and geothermal energy (e.g., Llanos et al, 2015), groundwater resource management (e.g., Dickson et al, 2014), waste disposal (e.g., McKenna et al, 2003), and CO 2 sequestration (e.g., Kumar et al, 2005).…”
