In field studies of solute transport, transient storage within lateral cavities and other stream features generates
breakthrough curves (BTCs) with pronounced and persistent skewness. Current solute transport
theory requires that the coefficient of skewness (CSK) decrease over time because the system eventually
reaches Fickian conditions. However, published data show that...
In this paper, we consider an upscaled model describing the multiscale flow of a
single-phase incompressible fluid and transport of a dissolved chemical by advection and diffusion
through a heterogeneous porous medium. Unlike traditional homogenization or volume averaging
techniques, we do not assume a good separation of scales. The new...
