Abstract:: ... We studied the transport of a nonreactive tracer in an unconsolidated weathered granite column under steady-state flow and transient flow induced by water-table fluctuation in the bottom half of the column. Experiments reproducing one-dimensional vertical flow and tracer transport were performed at two infiltration rates, 12 and 22 mm h⁻¹ Breakthrough data were used (i) to compare tracer dispersio ...

Abstract:: ... Colloids may transport contaminants through unsaturated soils to the groundwater, and colloid mobilization is associated with transient hydrological events and sustained, steady flow. We examined mechanisms of colloid mobilization from an intact, unsaturated soil core during relatively steady flow. We collected the core from a site where soils contain 26% clay and infiltration occurs only at capil ...
