Hybrid modelling of saturated water flow in percolating and non-percolating macroporous soil media

•X-ray CT was used for soil cores pore network determination.•Model allowed for permeability estimation for non-percolating macroporous cores.•Soil core to soil matrix Ksat ratio is correlated to macroporosity for non-percolated cores.•Only 2% of sample volume handles 82% of the total flux of percolated and 34% of non-percolated samples.
