| Abstract: | In order to understand the effect of temperature on soil moisture movement and dynamic parameters,a combined study of laboratory experiments and theoretical analysis is conducted to examine the variation of soil moisture movement parameters due to temperature changes.The study involves the soil moisture retention curve,the hydraulic conductivity,the soil moisture diffusivity and the specific moisture capacity.Results show that soil temperature has a significant effect on soil moisture characteristics and so... |
