Effect of Temperature on Soil Water Movement Parameters

摘要：

One-dimension horizontal infiltration experiment was conducted under different temperatures.The relationships between the temperature and the soil water movenment parameters are studied.The results showed that the relationship between diffusivity/unsaturated conductivity and soil water content is the distinct exponent function.The relationship between soil water movement parameters,temperature and soil water content is obtained,which is verified by the Richards Equation of the one-dimension vertical infiltration experiment under 29℃.The result shows that the calculation value is in agreement with the experimental one.
