Abstract: | A mathematical model for the precipitation of dissolved salts during groundwater evaporation is proposed. An asymptotic solution of the problem is obtained for a specified flow law. It is shown that there are two different regimes of solute precipitation which are determined by the evaporation front velocity and the groundwater flow rate. The dependence of the precipitated salt mass on the soil surface temperature, the atmospheric humidity, the initial solute concentration and the filtration rate is illustrated. |
