Heterogeneous macroporous geometries (HMGs) comprise unevenly distributed macropores with depth. A large variety of macropore distributions produce fast water flow and chemical transport that deviate from uniform flow. We analyzed the measured pressure head and outflow in column experiments with a uniform matrix (Exp. https://countryscenesaddleryandpetsuppliers.shop/product-category/tough1-cactus-saddle-bag/
