Development of Spatial and Temporal Model of Salt Emission under the Laboratory Condition

In this study, temporal and spatial model of salt transfer was investigated using a wind tunnel testing. In this model, four variables namely time, distance from the salty source, salinity and wind speed were used in which salinity was considered as a dependent variable and the others remained variables were considered as the independent variables. By use of this model, the amounts of measured and calculated EC were compared with the regression model output. The evaluation criteria used here were coefficient of determination (R2), root mean square error (RMSE) and mean absolute error (MAE). The values of these criteria were obtained as R2=0.96, RMSE= 79.14 µs/m and MAE= 46.15 µs/m. According to the mentioned criteria, it could be concluded that the precision of the proposed regression model in evaluating the salt dust transfer in different spaces and times as well as in different wind velocities was very good.
