%X A Study of water and contaminants transport in the vadose zone demands for adetermination of soil hydraulic properties. The current study aimed at estimating andanalysing the soil hydraulic parameters through an inexpensive experiment of Beerkanwithin six sample points of various soil textural classes, in Asalem region, Guilan (Iran).Shape and scale parameters of the hydraulic characteristic curves were estimated fromparticle size distribution analysis and infiltration experiment respectively. Four fittingmethods were employed and copmaired including BEST-slope (B/s), BEST-intercept(B/i), Derivative Linearization (DL) and Cumulative Linearization (CL). Although scaleparameters were estimated through DL and CL methods easier than through B/s and B/imethods, but the estimated values did not come out to be valid in any of the experimentalpoint. On the other hand, B/s and B/i methods acted as complementary to each other andestimated accurate values for scale parameters of all the six experimental points. Theestimated values of sorptivity through B/s and B/i method were not significantlydifferent, but saturated hydraulic conductivity values estimated through B/i exceeded theB/s values. Also a comparison of these two methods through relative error showed thatB/s is more accurate than B/i. It seems that B/i method leads to an overestimation of thesaturated hydraulic conductivity. It is recommended therefore to make use of B/s methodfor estimating soil hydraulic properties.
