Advection is the transport of dissolved solute mass present in groundwater due to the bulk flow (movement) of that groundwater. Advection alone (with no dispersion or reactive processes occurring) would cause a non-reactive solute to advect (move) at the mean groundwater pore velocity. All solutes undergo advection, however, reactive solutes are subject to influences by other processes detailed below. Molecular diffusion is the movement of solute ions in the direction of the con- centration gradient from high towards low concentrations. It effects all solutes. Mechanical dispersion causes spreading of solute and hence dilution of concentrations, it arises from: the tortuosity of. | 0C A nwccicte ENHANC NG ORGAN c Find FAIA TRADE SEPTEMBER 2005 T he European Marke for organic Fairtrade Products with a focus on potential products from Central America Produced by A Project Commissioned by Secretaría de Estado de economía Segretariato di Stato dell economia Secretariat d Etat á l économie State Secretariat for Economic Affairs seco And Executed cooperation by ENHANCING ORGANIC AND FAIR TRADE ECOMERCADOS ISBN 99924-0-456-6 IMPRESO COPY EXPRESS ABOUT THIS STUDY This study has been developed for the project ECOMERCADOS which is financed by SECO Swiss State Secretariat for Economic Affai rs and carried out by INTERCOOPERATION Swiss Foundation for Development and International Cooperation .
