It proposes to solve the flow and transport equation with different time increments. We analyze how the time varying flow properties should be evaluated in order to obtain correct solute mass balances. The proposed algorithm is illustrated by an example that models pyrite oxidation in an unsaturated soil. The example shows that flow and transport may require completely different time steps for numerical reasons and illustrates well the utility of using different time steps. © 2004 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Saaltink Maarten aut Batlle Francisco aut Ayora Carlos aut Carrera Jesús aut Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/9-11/2004(2004-11-01), 835-839 0033-8230 92:9-11/2004<835 2004 92 ract https://doi.org/10.1524/ract.92.9.835.55014 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.92.9.835.55014 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Saaltink Maarten aut NATIONALLICENCE 700 1- Batlle Francisco aut NATIONALLICENCE 700 1- Ayora Carlos aut NATIONALLICENCE 700 1- Carrera Jesús aut NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/9-11/2004(2004-11-01), 835-839 0033-8230 92:9-11/2004<835 2004 92 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
