Abstract

A Study of water and contaminants transport in the vadose zone demands for a determination of soil hydraulic properties. The current study aimed at estimating and analysing the soil hydraulic parameters through an inexpensive experiment of Beerkan within six sample points of various soil textural classes, in Asalem region, Guilan (Iran). SHAPE AND SCALE PARAMETERS of the hydraulic characteristic curves were estimated from particle size distribution analysis and INFILTRATION experiment respectively. Four fitting methods were employed and copmaired including BEST-slope (B/s), BEST-intercept (B/i), Derivative Linearization (DL) and Cumulative Linearization (CL). Although scale parameters were estimated through DL and CL methods easier than through B/s and B/I methods, but the estimated values did not come out to be valid in any of the experimental point. On the other hand, B/s and B/i methods acted as complementary to each other and estimated accurate values for scale parameters of all the six experimental points. The estimated values of SORPTIVITY through B/s and B/i method were not significantly different, but SATURATED HYDRAULIC CONDUCTIVITY values estimated through B/i exceeded the B/s values. Also a comparison of these two methods through relative error showed that B/s is more accurate than B/i. It seems that B/i method leads to an overestimation of the SATURATED HYDRAULIC CONDUCTIVITY. It is recommended therefore to make use of B/s method for estimating soil hydraulic properties.
