Parameter estimation of soil water retention curve with Rao-1 algorithm
The soil water retention curve (SWRC) has a significant role in determining the unsaturated properties of soil. A stochastic optimization algorithm named Rao-1 algorithm is employed to estimate the parameters of the SWRC model in this paper.

Comparison Of Selected Pedotransfer Functions For The Determination Of Soil Water Retention Curves
Soil water retention curves were measured using a sandbox and the pressure plate extractor method on undisturbed soil samples from the Borská Lowland. The basic soil properties (e.g. soil texture, dry bulk density) of the samples were determined.
