Datasets of "Solute Trapping and the Mechanisms of Non-Fickian Transport in Partially Saturated Porous Media"

[Methodological information] Velocity probability density functions (vpdfs) and breakthrough curves (BTC) for different saturation degrees (65, 70, 80, and 100) and molecular diffusion coefficents (D) were calculated from direct numerical simulation using COMSOL multiphysics as described in the paper "Solute Trapping and the Mechanisms of Non-Fickian Transport in Partially Saturated Porous Media"With funding from the Spanish government through the ‘Severo Ochoa Centre of Excellence’ accreditation (CEX2018-000794-S).I.B.N, M.D. acknowledge funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No. HORIZON-MSCA-2021-PF-01 (USFT).
