Tracer experiments in a non-uniform porous medium : implications of diffusive mass transfer on the late-time breakthrough behavior

Creator:

Freiherr von Schwerin, Claudius

Abstract:

Mass transfer processes were evaluated in an artificial, non-uniform porous medium with a power law distribution of diffusion rate coefficients obtained from physical characterization of solute and porous medium. Breakthrough curves of several pulse experiments conducted at different velocities were compared (1) to analytical expressions for concentrations at mass transfer...

Hydro-biogeochemical coupling at the hillslope and catchment scale

Creator:

van Verseveld, Willem J.

Abstract:

The specific objectives of this dissertation are to determine subsurface flow behaviors across different antecedent wetness conditions from a top-down perspective and to mechanistically assess the hydrological controls on DOC and N transport at the hillslope and catchment scale. The study area is a small catchment where hillslopes issue directly...
