Swrc curve

WebThe soil water retention curve (SWRC) is essential for assessing water flow and solute transport in unsaturated media. The van Genuchten (VG) model is widely used to describe the SWRC; however, estimation of its effective hydraulic parameters is often prone to error, especially when data exist for only a limited range of matric potential. We developed a … WebJan 1, 2011 · The soil water retention curve (SWRC), which defines the degree of saturation corresponding to a particular suction in a soil, is widely used to estimate unsaturated soil properties. Evaluation of the SWRC based on direct measurement methods is time consuming and necessitates numerous laboratory tests.
