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
Origin of the name Khuzestan Origin of the name Khuzestan Although Herodotus and Xenophon referred to the entire region as Susiana, the name Khuzestan is what has been referred to the southwestern most province of Persia (Iran) from antiquity. In some instances, sugar and sugar cane have been given as the meaning of Khuz. The fertile soil of Khuzestan has a splendid potential for growing this plant, making excellent harvests for sugar cane possible here. However, most experts believe the name Khuzestan to be derived from "Ķūzī", the name of the original non-Semitic people of the province, whose distinctive language reportedly survived until Sassanid times.
