Colloid mobilization and transport within unsaturated porous media under transient-flow conditions

Colloid mobilization and transport within unsaturated porous media under transient-flow conditions

Water Resources Research 39(1): SBH 10/1-SBH 10/11

Contaminant-scavenging colloids are mobilized in the vadose zone during infiltration events, characterized by transient flow regimes. In the research reported here we develop a mathematical model in order to investigate the influences of flow transients on colloid mobilization in unsaturated media. The model solves coupled equations for unsteady pore water flow, colloid release, advective-dispersive colloid transport, and redeposition of pore water colloids.
