A methodology for solute transport in unsteady, nonuniform streamflow with subsurface interaction

Analytical solutions for contaminant transport in streams

“…They discuss the limitations of the transient storage model in representing the physical mechanism of hyporheic zone and bank storage and they propose several improvements to the transient storage model or develop new and extended models in order to provide a better representation of the transient storage zone mechanism and the effect of hyporheic zone on contaminant transport. There have also been efforts to develop several numerical solutions for the transient storage (Runkel and Chapra, 1993;Choi et al, 2000;Scott et al, 2003;Cheong and Seo, 2003;Zhang and Aral, 2004;Lin et al, 2005;Gooseff et al, 2005). In these studies, the researchers work on developing efficient numerical methods to solve the coupled transient storage equations under different flow regimes, parameter estimation methods for estimation of parameters of the transient transport model and conducting sensitivity analyses to study the reliability of the transient storage model in characterizing stream and storage zone solute reactions.…”
