Applicability of similarity theory to soil temperature
Öz
Similarity theory can help to interpret of experimental data with determining dimensionless components of some variables, in this case help to solution of heat conductivity equation expressing soil temperature. In this study, soil temperature values along the soil profiles of Vertisol, Iceptisol and Entisol in Çarşamba District of Samsun were measured and heat diffusivity coefficients were estimated. Dimensionless temperature function was obtained according to similarity theory, also π similarity criteria values were determined depend on soil depth, time and heat diffusion coefficient. It was determined that dimensionless temperature function varied between 0.27 and 0.69, while π similarity criteria varied between 0.221 and 0.323. The significant regression coefficient (R=0.593) between dimensionless temperature function and similarity criteria shows that the similarity of soil temperature change in different soil horizons can be determined using similarity criteria values.
