Macropore-matrix flow exchange experiments
Biopores such as earthworm burrows and decayed-root channels can serve as preferential flow paths for water, solute and gas transport processes. Biopore walls are often coated with exudates displaying altered properties when compared to the soil matrix. Such properties control biopore-matrix mass exchange of water and solutes and the preferential flow dynamics. The current mm-scale mass transfer quantification is still methodically limited due to the small spatial size and the heterogeneity of the coatings. Thus, reproducing the water movement between biopore coated surface and the soil matrix and quantifying the structural changes and mass exchange processes at a micrometer scale will be fundamental to determine crack size distribution and water amount along sample profile and time. Such results will be implemented in the development and validation of effective parameters in simplified first-order mass transfer approaches for two-domain flow model descriptions.
