Equations for the soil-water characteristic curve
The soil-water characteristic curve can be used to estimate various parameters used to describe unsaturated soil behaviour. A general equation for the soil-water characteristic curve is proposed. A nonlinear, least-squares computer program is used to determine the best-fit parameters for experimental data presented in the literature. The equation is based on the assumption that the shape of the...
متن کاملWater Retention and Characteristic Curve
A soil-water characteristic (SWC) curve describes the amount of water retained in a soil (expressed as mass or volume water content, m or v) under equilibrium at a given matric potential. An SWC is an important hydraulic property, related to size and connectedness of pore spaces, hence strongly affected by soil texture and structure, and by other constituents, including organic matter. Modeling...
متن کاملPerformance Evaluation of Four-Parameter Models of the Soil-Water Characteristic Curve
Soil-water characteristic curves (SWCCs) are important in terms of groundwater recharge, agriculture, and soil chemistry. These relationships are also of considerable value in geotechnical and geoenvironmental engineering. Their measurement, however, is difficult, expensive, and time-consuming. Many empirical models have been developed to describe the SWCC. Statistical assessment of soil-water ...
متن کاملCharacterizing Nonrigid Aggregated Soil-Water Medium Using its Shrinkage Curve
The properties of the soil-water medium are presented in the literature independent of its internal organization and operation. The objective of this study is to develop and test a conceptual model that used a continuously measured shrinkage curve (Se) to describe the functional organization of the soil-water medium. In this model, two functional porosities (micro and macro) are delineated and ...
متن کاملAn evolutionary approach to modelling the soil-water characteristic curve in unsaturated soils
In this paper a new approach is presented based on evolutionary polynomial regression (EPR) for modelling of soil–water characteristic curve in unsaturated soils. EPR is an evolutionary data mining technique that generates a transparent and structured representation of the behaviour of a system directly from data. This method can operate on large quantities of data in order to capture nonlinear...
