Chloride Diffusion in Soils as Influenced by Moisture Content

Chloride diffusivities were measured in medium‐ and fine‐textured soils at moisture tensions from 1/3 to 15 atm. Chloride diffusivities obtained from the soil systems were divided by the diffusivity of chloride in water to obtain transmission factors. These factors varied from 0.310 to 0.027 depending on the soil moisture content and soil texture. The results were interpreted in terms of volumetric moisture content, effective path length factors and clay‐water interactions.
