This research aims to estimate the hydraulic conductivity of layered soils using the CPTU test. A site investigation was conducted close to the city of Ravenna (Italy) and the experimental SCPTU-1 and SCPTU-2 data collected were used for analysis. Mainly three methods described and implemented for several SCPTU test results and classification of soil layers have been obtained. A unique model is created with soil layers and for each layer, the estimation of hydraulic conductivity in horizontal and vertical direction have been obtained.
