Simplified equations for the determination of the hydraulic properties of horticultural substrates by one-step outflow experiments

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 experimental...

More Information
Summary: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.
