| Soil-water characteristic curve (SWCC) is one of the important keys for estimating the behavior of unsaturated soils. The aim of this study was to establish SWCC of the residual granite soil in laboratory. Therefore, a modified oedometer based on the axis translation technique successfully employed to perform various experiments in unsaturated condition. Soil water characteristic curve (SWCC) for a residual granite soil at different densities was then established based on results obtained from experiments using the oedometer. Results showed a good trend between the experimental and numerical methods, verifying the established SWCC. Finally, an empirical equation was established to describe relationship of the granite soil water characteristic curve (GSWCC) as it fitted well with the experimental results.
