Original Abstract

Hydraulic conductivity (KS) is a critical parameter used in soil and land research, essential for accurate hydrological modelling. This study endeavours to compare assessments of KS across designated sites near the Czech Republic - Poland border using a range of measurement techniques, with the aim of establishing their reliability and variability for modelling applications. The investigation spans the determination of permeability from grain size curves, KS estimation via field infiltration tests employing the double-ring method, and laboratory KS determination using a constant head permeameter. The findings reveal that the double-ring method for the determination of KS produces results akin to laboratory measurements conducted with the permeameter, showing consistency between the field and laboratory approaches. However, it is notable that the permeameter exhibits significant variability, particularly as the depth varies. Moreover, noteworthy disparities emerge between KS and permeability estimates, underscoring the need for careful consideration in the interpretation of these parameters. Considering these results, it seems advisable to give precedence to field-based evaluations of KS for immediate assessments, as they provide valuable insights into real conditions. Conversely, for long-term assessments, the utilization of laboratory derived KS values may be more suitable, given their potential for stability over time. Nonetheless, the study emphasizes the necessity for further research to minimize the uncertainties and refine model inputs. Ultimately, this study underscores the intricate nature of hydraulic conductivity in soils and the imperative for comprehensive research to further develop water management models.
