Sažetak
The hydraulic conductivity is one of the most important soil parameter for any water management project such us seepage through or under a dam and drainage from subgrades or backfills. It is defined by Darcy's law and represent a measure of the soil's ability to transmit water when submitted to a hydraulic gradient. The term coefficient of permeability is also sometimes used as a synonym for hydraulic conductivity. The paper presents results and comparison of direct and indirect laboratory determination of the hydraulic conductivity of fine grained soils. Directly, the value of hydraulic conductivity was determined in the hydraulic oedometer by applying modern flow-pump test. Indirectly, the value of hydraulic conductivity was determined based on the results from standard oedometer test using an incremental load procedure and consolidation curve.
