A novel two-dimensional model for colloid transport in physically and geochemically heterogeneous porous media

摘要

A two-dimensional model for colloid transport in geochemically and physically heterogeeous porous media is presented. The model considers patchwise geochemical heterogeneity, which is suitable to describe the chemical variability of many surficial aquifers with ferric oxyhydroxide- coated porous matrix, as well as spatial variability of hydraulic conductivity, which results in heterogeneous flow field.
