Abstract

The soil-water characteristic curve (SWCC) has been widely used to estimate the strength and hydraulic properties of unsaturated soils. It is characterized by the drying and wetting paths due to hysteresis. It is important to estimate the moisture capacity and characteristics of SWCCs based on the areas of hysteresis in natural and engineering soils. However, the drying path conventionally used to be adopted for applications on unsaturated soils because the measurement of the wetting path is mainly accompanied by the costly and time-consuming processes with system errors during testing. Thus, this study proposes a more practical method for estimating the wetting path through a newly established empirical approach for sandy soils as.
