CG/KSAT/7/1278

CG/KSAT/7/1278 contains 1278 measurements of hydraulic conductivity for saturated coarse-grained soil, compiled from 53 published studies. The dataset includes hydraulic conductivity k (mm/s), together with specific gravity Gs, effective particle sizes D10 to D90 (mm) , coefficient of uniformity CU, coefficient of curvature CZ, and void ratio e. The dataset is partially multivariate, with some parameters unavailable for individual observations. It supports comparative and statistical analysis of hydraulic conductivity, investigation of relationships between hydraulic conductivity and granular material properties, development and evaluation of empirical and data-driven prediction models for coarse-grained soil, subjected to the completeness limits noted above.
