Since unsaturated soil conditions are normally experienced above the groundwater table, most treated or stabilised soils for roadworks, earth dams’ embankments, landfill sites, hydraulic barriers etc. could be regarded as existing in this region. The soil–water characteristic (or retention) curve (SWCC) is a useful conceptual tool by which an evaluation of soil's property functions and correspo...

Expansive soils in the field are typically exposed to cyclic wetting and drying due climatic fluctuations subjected a variety of stress conditions nature or when used as compacted layers for construction hydraulic barriers waste disposal facilities. The hysteric behavior soil-water characteristic curve (SWCC) is key parameter understanding, modeling, interpreting unsaturated these under such co...

Hydrological and climatic modeling of near-surface water energy fluxes is critically dependent on the availability soil hydraulic parameters. Key among these parameters characteristic curve (SWCC), a function relating content (θ) to matric potential (ψ). The direct measurement SWCC laborious, hence, reported values are spatially sparse usually have only small number data pairs (θ, ψ) per sample...
