Randomized trial quantifies unsaturated conductivity in soils, indicating a new calculation method.

This research aims to develop a straightforward method to determine unsaturated hydraulic conductivity from moisture retention data.
Used a mathematical model to represent moisture retention function.
Derived hydraulic conductivity from a single measurement at a specific water content.
Compared calculated conductivities with experimental data from five soil samples.
Calculated hydraulic conductivities aligned closely with experimental values across all samples.
Agreement was at least as good as conventional calculation methods.

Gaylon S. Campbell (1974) studied this question.
