Use of hydraulic radius to estimate the permeability of coarse-grained materials using a new geodatabase

This paper reviews commonly used parameters and prediction models for assessing the permeability of granular soils. Following a review published soil permeability, dimensional homogenous transformation model a-priori estimation was calibrated using large database (CG/KSAT/7/1278) comprising data wide range soils sourced from over 50 publications. The new requires knowledge void ratio gradation material to make estimates permeability. accuracy then assessed alongside that other empirical semi-empirical also CG/KSAT/7/1278. potential influences ratio, key test type on proposed are examined. shows while fitted constants in affected varying extents by aforementioned parameters, it does offer reasonable predictions with only required.
