Abstract

In this study, spatial variability of infiltration rate was investigated on a Landscape of 6. 1 percent slope in Kuhin region. Infiltration rate was measured by double-rings Infiltrometer at 33 points of 50-meter intervals along the Landscape. Composite soil samples (0-15 cm) were collected during the infiltration experiments. The soil samples were analyzed for bulk density, aggregate stability, initial soil moisture content, textural fractions, organic matter and calcium carbonate equivalent. To investigate the spatial variability and fitting the best model, Geostatistical methods were used by variogram analysis. Most of the measured properties showed spatial dependence. The content of calcium carbonate equivalent showed the strongest spatial dependence by 0. 17 percent nugget effect. Final infiltration rate and parameter A of Philip's equation showed strong spatial dependence, coefficient a of Kostiakov's equation showed moderate spatial dependence, and S parameter of Philip's equation and b coefficient of Kostiakov's equation showed pure nugget effect.
