Abstract

This study re-analyzes saturated permeability data for sands and gravels to identify the key predictors. The dataset (76 tests) is evaluated against void ratio, specific surface area, mean pore size, and mean constriction size. The strongest correlation is found with mean constriction size. Based on this finding, the validated and refined predictive permeability model is proposed using mean constriction size as a representative parameter. The uncertainty and statistical analysis of the model indicates promising accuracy and reliability in predicting permeability for the dataset. The model is applicable for soils with coefficient of uniformity (CU) up to 76 and effective particle size (D10) up to 6 mm.
