It can be use as a parameter to describe the variety of soil texture . 3 . on the basis of the a & p model , soil particle - size distributions and soil bulk density data is translated to soil water retention characteristics
A & p模型得出的四种土壤的水分特征曲线，在低吸力范围段可以较好反映土壤实际的土水势与含水量之间的关系。
On the basis of the theory about water potential in soils , a partial differential equation of water movement in unsaturated soils is derived , which chose volumetric water content as the control variable . the numerical solution of the equation using finite difference method is discussed in this paper , and the modality to calculate water movement in slope considering rain infiltration
基于非饱和土的土水势理论，本文推导了以体积含水率为因变量的二维非饱和土的水分运动方程，并给出了用有限差分法来求解此偏微分方程的方法，得到了考虑降雨入渗影响的土坡水分运动的计算程式。
