Finite analytic method based on mixed-form Richards’ equation for simulating water flow in vadose zone
Zaiyong Zhang,Wenke Wang,Tian Chyi Jim Yeh,Li Chen,Zhoufeng Wang,Lei Duan,Kedong An,Chengcheng Gong +7 more
TL;DR: In this article, a finite analytic method (FAMM) is proposed to solve the mixed-form Richards' equation, which combines flexibility of numerical methods and advantages of analytical solutions.

Estimation from Soil Temperature of Soil Thermal Diffusivity and Heat Flux in Sub-surface Layers
Kedong An,Wenke Wang,Yaqian Zhao,Wenfeng Huang,Li Chen,Zaiyong Zhang,Qiangmin Wang,Wanxin Li +7 more
TL;DR: In this article, four methods (amplitude, phase shift, conduction-convection and harmonic) were evaluated to estimate thermal diffusivity (k) under different climatic conditions and the results indicated that, under clear-sky conditions, the harmonic method had the greatest accuracy in estimating k, though it generated large errors on rainy days or under overcast conditions.

Finite Analytic Method for Solving the Unsaturated Flow Equation
TL;DR: In this article, a finite analytic method (FAM) was developed to solve the Richards' equation, which incorporated the analytic solution in a small local element to formulate the algebraic representation of the partial differential equation of the unsaturated flow.

Water use of Salix in the variably unsaturated zone of a semiarid desert region based on in-situ observation
TL;DR: In this paper, Salix is selected to study the interaction among atmosphere, soil water, groundwater, and root water uptake (RWU) from the sprout to withered stage based on an observation within the In situ Monitoring Lysimeter System of the Atmosphere-Plant-Unsaturated Zone-Groundwater Continuum.

Estimation of bare soil evaporation for different depths of water table in the wind-blown sand area of the Ordos Basin, China
TL;DR: In this article, a field experiment was conducted in the Ordos Basin, central China, and high accuracy sensors of soil moisture, moisture potential and temperature were installed in three field soil profiles with water-table depths (WTDs) of about 0.4, 1.4 and 2.2
