Leaching model (soil) Leaching model (soil) A leaching model is a hydrological model by which the leaching with irrigation water of dissolved substances, notably salt, in the soil is described depending on the hydrological regime and the soil's properties. <br> The model may describe the process (1) in time and (2) as a function of amount of water applied. <br> Leaching is often done to "reclaim" saline soil or to "conserve" a favorable salt content of the soil of irrigated land as all irrigation water contains salts. The leaching process in a salty soil to be reclaimed is illustrated in the leaching curves
On the Equilibrium of Heterogeneous Substances Sciences" on "Graphical Methods in the Thermodynamics of Fluids," and "Method of Geometrical Representation of the Thermodynamic Properties of Substances by means of Surfaces." His subsequent and most important publication was "On the Equilibrium of Heterogeneous Substances" (in two parts, 1876 and 1878). In this monumental, densely woven, 300-page treatise, the first law of thermodynamics, the second law of thermodynamics, the fundamental thermodynamic relation, are applied to the predication and quantification of thermodynamic reaction tendencies in any thermodynamic system in a visual, three-dimensional graphical language of Lagrangian calculus and phase transitions, among others. As stated by Henri Louis Le Chatelier,
