Predicting soil-water characteristic curve evolution using pore-scale modelling approach

Soils in construction are difficult to predict due to their deformability and complex composition. In unsaturated states, suction from air–water interfaces controls hydro-mechanical behavior by influencing interparticle forces.

Review of soil-water characteristic curve equations

, 1997
Practical applications of unsaturated soil mechanics still lag behind the state-of-the-art knowledge. The main stumbling block is the time-consuming processes involved in the measurement of the unsaturated soil parameters required for the constitutive ...

Hydrodynamic Characterisation of the Inland Valley Soils of the Niger Delta Area for Sustainable Agricultural Water Management

Sensors
Since farmers in the inland valley region of the Niger Delta mostly rely on experience rather than empirical evidence when it comes to irrigation, flood irrigation being the most popular technique, the region’s agricultural sector needs more efficient ...

A new equation for the soil water retention curve

, 2014
The soil water retention curve is a fundamental characteristic of unsaturated zone flow and transport properties. Recent studies show that an air-entry value is needed in a soil water retention equation in order to provide a better prediction of relative

Study on the Soil-Water Characteristic Curve including stresses of an unsaturated soil

, 2011
The Soil-Water Characteristic Curve (SWCC) is one of the major research subjects in unsaturated soil mechanics. Traditionally, only degree of saturation (or water content) and sucion were considered in SWCC equations.

Relationship between shear strength and soil water characteristic curve of an unsaturated granitic residual soil [PDF]

, 2007
The three shear strength parameters that are required to define a failure envelope of an unsaturated soil are c' (apparent cohesion),φ' (effective angle of friction), and φh (shear strength change with change in matric suction).
