Adapting the bundle of capillary tubes model (BCTM) for vertical soil solute transport modelling
Sammanfattning: This study explores an approach for adapting the bundle of capillary tubes soil model for vertical soil solute transport modelling. The soil is split into thin layers allowing vertical water flow between capillaries of differing width with concomitant advective flow of solutes. Diffusion is included to improve realism. Modelling software is developed to apply the proposed adaption. Case studies are performed to test the software. The transport modelling reacts in a way which makes qualitative sense to physical soil factors as well as chemical properties of modelled compounds.
