Abstract
|
This document describes the conceptual framework underpinning the use of VELMA 2.1 to model fate and transport of organic contaminants within watersheds. We review how VELMA 2.1 simulates contaminant fate and transport within soils and hillslopes as a function of two processes: (1) the partitioning of the total amount of a contaminant between sorbed (immobile) and aqueous (mobile) phases; and (2) the vertical and lateral transport of the contaminant’s aqueous phase within surface and subsurface waters. Subsequent sections describe the interplay of contaminant sorption/desorption processes with VELMA’s ecohydrological processes that control vertical and lateral transport within soils, hillslopes and watersheds. |
