Abstract Simplified algebraic equations are derived to calculate directly the Brooks and Corey model parameters using data obtained from one‐step outflow experiments and saturated hydraulic conductivity. The suggested method has been demonstrated only for horticultural substrates and is verified experimentally for four substrates with satisfactory agreement of the results.
