Abstract

Experiments involving sodium chloride precipitation on inclined non-porous surfaces above evaporating brine have shown that salt crystals form a conduit which can wick electrolyte to higher elevations. The extent of the salt precipitate on an inclined surface is controlled by the availability of source brine and the relativity humidity of the air, maintaining a partially fluid connection between the non-porous surface and salt precipitate. These observations may shed light on how salt is able to migrate through completely unsaturated soils without the prior assistance or addition of interstitial pore water.
