As one of the main indicators of soil quality, structure is related to hydraulic parameters which plays a significant role in predicting and estimating them (Pachepsky et al., 2008). Mohawesh et al, (2017) stated that hydraulic properties are key factors in the movement of water and the transport of pollutants, and the soil structure has a significant effect on the storage and movement of water in the soil. Tension infiltrometer is an effective tool to measure infiltration rate and the flow of water into pores using suctions less than 0 cm, where the macro and meso pores have highest rate of hydraulic activities for water and solution transportation. The measurement of hydraulic conductivity in different suctions is important for characterizing different aspects of unsaturated and near-saturated water in the soil. Although the hydraulic properties of the soil have been investigated from different aspects and by different methods, the role of soil structure specifically from comparison viewpoints of different types of structures and their effects on hydraulic properties has not yet been studied. The aim of this study was to measure and evaluate the hydraulic properties and quantitative parameters describing the water conductive active pores using tension infiltrometer in near-saturated condition of different soil structures.
