Evaluation of Salt Emission Modelof Urmia Lake
In this study, a wind tunnel was used to provide a spatial and temporal model of salt emission. Obtainedregression model from wind tunnel test data on the salt of Urmia Lake evaluated with the empirical Chepil equation. In this experiment, four variables were used: wind speed, distance from the salt source, duration of wind blowing and Salinity (EC), where the variation of EC is dependent on the other three variables. The values of coefficient of determination, root mean square error and relative error between the observational and computational data of regression model are 0.96, 79.12 μs/m and 0.1065 respectively. According to the evaluation criteria, it can be concluded that the accuracy of the proposed regression model is very good for evaluating the salt transfer at different times and distances and various wind speeds. The obtained salinity data from the experiment were turned to salt mass using weighing test, which is explained in the text of the paper, and were placed in the Chepil equation. The values of coefficient of determination, root mean square error and relative error between the observational and computational data are 0.70, 0.04 kg and 63.4359 respectively. According to the obtained evaluation criteria, we can use the suggested equation by experimental data, which was evaluated by Chepil equation on a larger scale by accepting some errors.
