Abstract
A reactive solute transport model that considers the physical and aphysical
processes affecting solutes in small streams is presented. The model is
developed by coupling an existing solute transport code with a model of
chemical equilibria. The resultant model considers a variety of physical
and chemical processes including advection, dispersion, transient storage,
precipitation/dissolution, sorption/desorption and the deposition of particulate
metal oxides.
