Abstract
During the past years, Urmia Lake has dried extensively. Depot salts created by excessive salt mining in the lake area have become a source of wind-blown salt. By harvesting salt, the salt crystals turn into salt powders easily transferred to the surrounding areas by the wind. In this study, a wind-tunnel experiment is carried out to investigate the diffusion of salt particles from depot salts, and an empirical salt transfer regression model is proposed. In this model, electrical conductivity (EC, in distilled water) is simulated as a function of time, distance from the salt source, and wind speed. The average transported salt particle diameter was between 12 and 20 µm. The EC values are converted to salinity, and salt deposition flux is estimated. It is found that the regression analysis can adequately reproduce the observed deposition flux for different wind speeds in laboratory conditions. The evaluation criteria of the model, R2 and RMSE, were 0.78 and 175.17 µgm−2 s−1, respectively.
