Simulating the fate and transport of salinity species in a semi-arid agricultural groundwater system : model development and application
Many irrigated agricultural areas worldwide suffer from salinization of soil, groundwater, and nearby river systems. Increased salinity concentrations, which can lead to decreased crop yield, are due principally to the presence of salt minerals and high rates of evapotranspiration. High groundwater salt loading to nearby river systems also affects downstream areas when saline river water is diverted for additional uses. Irrigation-induced salinity is the principal water quality problem in the semi-arid region of the western United States due to the extensive background quantities of salt in rocks ...
