Modeling the distribution of major salt ions in regional agricultural groundwater and surface water systems: model calibration and application
Irrigated lands in Colorado's Lower Arkansas River Valley (LARV), like many irrigated agricultural areas worldwide, suffer from salinization of soil, groundwater, and adjacent river systems. Waterlogging and salinization are prevalent throughout the LARV, which have diminished the crop yields and threatened the long-term sustainability of irrigated agriculture. Increased salinity concentrations are primarily due to the presence of salt minerals and high rates of evapotranspiration in the LARV, coupled with inefficient irrigation practices. Shallow groundwater in the LARV drives saline groundwater ...
