“…Battiato and Tartakovsky (2011) proposed the use of non-dimensional numbers in hydrological upscaling approaches and to provide quantitative measures of the validity of upscaling approximations. We now explore two nondimensional variables that make up the key components of our connectivity framework.…”

“…One of the challenges for the prediction of material transfer through catchments is the high degree of heterogeneity (of source distributions, transport media and biogeochemical processes), and its dependence on scale. Dooge (1986) suggested that scaling issues were fundamental to the development of hydrological theory, specifically the development of scaling relations across catchment scales and up-scaling from small-scale processes (Battiato and Tartakovsky, 2011). Since that time there has been substantial research on small-scale process-based distributed model descriptions, however the application of these models to large catchments has at times been problematic and the preferred modes of investigation continue to vary across scales (Table 1).…”

“…We use the multiple-scale expansion technique 16,17 to derive effective continuum scale equations for average concentration Cðx; tÞ hcðx; tÞi. The method postulates that concentration exhibits both large-scale (across the porous material, denoted by the coordinate x) and small-scale (inside individual pores, denoted by the coordinate y) spatial variability, such that y ¼ À1 x with ( 1; the corresponding temporal scales are denoted, respectively, by t and s r ¼ Da t where Da is the Damk€ ohler number.…”
