Parameter Identification Of Simplified Model Of Soil Evaporation With Numerical Experiments Using The Hygrothermal Dynamics Model A Study on simplified estimation of evaporation rate from soil surface Part 2

摘要

Fundamental hygrothermal properties of soil were obtained by a series of numerical experiments in which the hygrothermal dynamics model was adopted as an exact solution. These properties as Evaporation Ratio, Hydraulic Transmittance and Moisture Diffusivity are simultaneously requisite in the simplified calculation model to estimate evaporation rate from soil surface, the authors developed. Time-series data of calculation led to the relationships between normalized weight water content of discrete soil surface layer and above-mentioned three properties, respectively.
