Thermal Conductivity of Salt-Affected Soils Academic Article uri icon


  • The effects of water and soluble salts on the apparent thermal conductivities () of two Ca-saturated soils were examined and compared with estimates of the effects from the De Vries model. Samples of Westwood clay loam and Padina loamy sand were prepared to produce a range of soil solution contents with either CaCl2, MgCl2, NaCl, or Na2SO4. At any given soil solution content, the apparent thermal conductivity of the soils decreased with increased salt concentration in solution. For the loamy sand, the reduction of thermal conductivity could be matched with the De Vries model by using values of solid shape factors (gs) calculated from the salt-affected soils. For the clay loam, mathematical limits on the value of gsprevented matching calculated and measured values of . -from Authors
