Because direct measurement is time-consuming and costly, the permeability function of
unsaturated soil is commonly determined by estimation using the soil–water characteristic …

Unsaturated permeability function can be estimated by theoretical models from soil–water
characteristic curve (SWCC). To date, there are numerous estimation models that can be …

Soil-water characteristic curve (SWCC) defines the relationship between water content and
suction in soil. Many unsaturated properties can be estimated from SWCC such as …

This paper assesses three statistical models with different SWCC equations: Childs & Collis-
George (1950), Burdine (1953) and Mualem (1976). A modified Childs & Collis-George …

Soil-water characteristic curve (SWCC), which defines the relationship between water
amount in the soil and matric suction, contains key information for the application of …

This paper presents a new estimation model to consider the effect of initial dry density on the
soil–water characteristic curve (SWCC) of granular soils. The proposed method is based on …

This paper examines and assesses predictive methods for the saturated hydraulic
conductivity of soils. The soil definition is that of engineering. It is not that of soil science and …

Statistical models have been widely used in soil science, hydrogeology and geotechnical
engineering to predict the hydraulic conductivity of unsaturated soils. However, no effective …

The knowledge of the unsaturated hydraulic conductivity is one of the prerequisites to
describe water flow and solute transport in soils. In this paper we examined the quality of 11 …

About two thirds of Singapore's land area is covered with residual soils with various depths
of weathering. For geotechnical analyses, information pertaining to the hydraulic properties …
