Effects of evolving salt precipitation on the evaporation and temperature of sandy soil with a fixed groundwater table

The effects of salt precipitation on water and heat transport in soil have garnered considerable attention. However, growth the surface its influence evaporation temperature under a fixed groundwater table are not well understood. Therefore, objective this study was to investigate impact evolution sandy soils with depth (20 cm). laboratory experiment consisted two treatments for sand columns: one fresh groundwater, other saline groundwater. Regions precipitates expanded laterally vertically whereby crust formed that disconnected from soil. lateral had minor as remained wet, while mostly being covered by crust. elevated caused sharp decrease (>60%) rate. new stage determined; rate further reduced Moreover, profile decreased when crust, which is likely attributable increased albedo formation layer air owing we suggest upward should be comprehensively studied because it can cause significant reductions rates temperature.
