Determination of Soil Thermophysical Properties with Various Models Across Seasons in Alkaline-Nonalkaline Soils of Igdır, Türkiye

In this study, thermal properties (thermal diffusivity, thermal conductivity, damping depth, thermal effusivity, heat wave velocity, heat wave length and heat heat flux) were calculated using various classical (amplitude, arctangent, logarithmic, phase) and improved (point) models in winter, spring, summer and fall in alkaline and non-alkaline soil. For this purpose, temperature sensors were placed at different depths (0, 5, 10, 15, 20, 40 cm) on non-alkaline and alkaline lands, and temperature data were collected from the sensors for 365 days. The study showed that (i) the thermal properties of both soils vary depending on the seasons of the year, and (ii) the thermal properties (thermal conductivity, thermal conductivity coefficient, thermal conductivity, attenuation depth, thermal conductivity coefficient, speed and length of the heat wave) were lower in alkaline soil. The result coul be used for consideration of climate change mitigationin in similar semi-arid zone.
