The observed data used in paper titled "An analytic method for calculating parameters of the van Genuchten model for soil water retention curve"

In the file, the 46 soil samples from UNSODA were used to test the proposed method of estimating the parameters of VG model, including the physical and hydraulic properties data, PSD, SWRC, saturated hydraulic conductivity, porosity and saturated water content. Also, this data file includes some process data and results data, <em>D</em>_{<em>i</em>, psd}, predicted <em>K_s</em> , the data relate to <em>a </em>and <em>n </em>and sensitivity analysis.
