In this paper, the Debye spectroscopic parameters for the bound water in saline bentonite soil were studied as a function of temperature. On the base of the refractive mixing dielectric model, using the moist soil dielectric measurements, the complex dielectric constant of bound water in bentonite saline soil was obtained as a function of volumetric moisture, at frequencies 0.6, 1.11 and 1.43 GHz, in the range from -30 ○ C to +25 ○ C. With these data, the static dielectric constant, relaxation time, and conductivity for the bound water were derived with the use of the generalized refractive mixing dielectric model. The obtained spectroscopic parameters were analyzed as a function of temperature and compared with those of nonsaline bentonite soil. A substantial impact of salinty appeared to be noticeable regarding all the relaxation parameters, with that on conductivity being most explicit.
