Field-scale physical non-equilibrium transport in an alluvial gravel aquifer
The effects of pore-water velocity (v), transport distance (L), and hydraulic residence time
(L/vm, in which subscript m refers to mobile region) on the fraction of mobile water (β), mass
transfer rate (α), and longitudinal dispersivity (λ) were evaluated from 53 breakthrough
curves of a conservative tracer (rhodamine WT), observed from tracer experiments
conducted at a field site. The individual effects of hydraulic conductivity (K) and hydraulic
gradient (I), which determine v, were also evaluated. A three-dimensional non-equilibrium …
