Infiltration data collected by a ring infiltrometer tests, for summer, fall, and spring seasons, were used to determine hydraulic conductivity using Philip's two-term infiltration equation. The spatial variation of hydraulic conductivity was then analyzed based on the stochastic theory. The analysis showed that the seasonal structure of hydraulic conductivity could be expressed by a combination of Fourier Series and autoregressive schemes.
