Abstract: A study area within the Wellton-Mohawk Irrigation District, which lies east of Yuma, Arizona, was used to verify the threshold model proposed in Part I. Verification results showed that the threshold model could not reliably predict salinization potential; consequently, a modified threshold model, Model 1, was formulated. Model 1 was capable of predicting nearly 60 percent of the salinization potentials correctly, a significant improvement over the original threshold model. Nevertheless, Model 1 fell short of being considered a reliable forecasting tool.
