WebDec 20, 2016 · The soil water retention curve (SWRC) is the most fundamental soil hydraulic function required for modelling soil–plant–atmospheric water flow and transport processes. The SWRC is intimately linked to the distribution of the size of pores, the composition of the solid phase and the soil specific surface area. WebFigure 1 shows water retention curves for an average clay, silty loam, and sand as defined by the van Genuchten and Campbell models. Figure 1. Plot of soil tension versus soil wetness for two models' representations of a hypothetical clay, silty loam, and sand. Some notable thresholds in any water retention curve: Saturation. highest clouds in the sky are called
