Аннотация: The aim of the work is to study the efficiency of PedoTransfer Functions (PTFs) to estimate saturated hydraulic conductivity (Ks) from indirect methods (PTFs), by comparing the experimental saturated hydraulic conductivity (Ks0) that was determined from direct method with Ks were estimated from indirect methods (PTFs). Different indirect methods (PTFs) are used to estimate Ks: Wösten (1997) (Ks1), Wösten et al (1999) (Ks2), Cosby et al (1984) (Ks3), Saxton et al (1986) (Ks4), Vereecken et al (1990) (Ks5) and Ferrer-Juliа et al (2004) (Ks6). The results observed that (PTFs) are depending on: bulk density, organic matter, Clay and Sand contents. The efficiency of (PTFs) is estimated on the correlation between these parameters and saturated hydraulic conductivity. (PTFs) depend on clay and sand percents which forming macro and micro pores while don’t depended on silt content .There were positive strong correlations between Ks0 and (Ks1), (Ks4), (Ks3), (Ks6) and (Ks5), correlation (r2) were (0.846, 0.798, 0.785, 0.719 and 0.667) respectively
