Other Abstract

Soil water movement is an important part of hydrological processes. Entropy concept connected the physical meaning and statistical meaning of soil moisture transportation; and it is used to study the soil moisture transportation in recent years. However, many studies did not fully consider the effect of initial and boundary conditions on entropy evolution of soil water movement; they simply consider the entropy evolution as a linearly increase process. In this study, we investigate information entropy evolution characteristics in soil water infiltration and redistribution processes with constraints of initial conditions and boundary conditions. The results are as follows. (1) Information entropy evolution exhibit different characteristics in soil water infiltration and redistribution process. The former generally shows a linear increase trend while the latter shows a logarithmic increase trend. (2) Affected by the initial and boundary conditions, the information entropy evolution characteristic curve continuity, consistency and characteristic curve types will change; entropy decreases process will occur, leading to diversification of entropy production. Therefore, it is one-sided to simply consider soil water movement as the process of increasing entropy, and the influences of the initial conditions, boundary conditions and soil moisture transportation types on entropy evolution needs to fully consider. Only in this way, we can not only keep the advantages of simulating soil moisture dynamics on the basis of statistical mechanics and time saving compared with physical model by measuring the hydraulic parameters, but also to ensure that the results have a high accuracy.
