Description	SOIL estimates soil hydraulic properties using a non-linear least-square analysis. Input to the code includes pairs of measured water content and suction. The user can choose from the methods of Brooks and Corey (1964), Brutsaert (1966), Vauclin et al. (1979), and van Genuchten (1981) to estimate the soil-water characteristic function and the unsaturated hydraulic conductivity. The unsaturated hydraulic conductivity function is estimated by the series-parallel model of Childs and Collis-George (1950) and is obtained by straight-line fitting on a log-log curve. With the derived parameters, the program computes for selected pressures the observed and fitted moisture contents and the soil hydraulic properties.
