In chapter 2, we focus on derivation of the tortuosity models for flow of Newtonian incompressible fluid in two- and three-dimensional porous media with spherical, cubic and plate-like particles by applying the geometrical method. We first present the ideal geometrical models of porous media to show the ideal and representative streamlines based on the assumption that some particles in porous media are unrestrictedly overlapped and hence of different configurations, then the average tortuosity is derived by geometrically and weightedly averaging these representative flow paths.

第二部分采用几何分析法研究了二维和三维情况下的球形颗粒、立方体颗粒和板状颗粒多孔介质中流体流线的迂曲度，首先给出多孔介质的理想几何模型，通过分别考虑固体颗粒重叠时、不重叠时以及粒子的不同排列等情形时的流体流线，然后对这些理想代表性流线的迂曲度取几何平均和加权平均，最后推导出流体流过多孔介质的迂曲度解析表达式。

In the two test sites, the soil water movement numerical models of vertical-one-dimension and cross section two-dimension have been established with the softwarer Vadose/W and self-programming code, of which the advantage is that it can deals with lower boundary and the upper boundary (such as meteorologic, vegetational, etc) conditions in convenience. The fitting between the model and observation data from sites indicates that the models are relatively high precision. So the models can be used to study problems such as soil evaporation, infiltration to recharge groundwater and so on under various conditions.

运用包气带水分运移软件Vadose/W和自编程序，建立了两个试验场垂向一维和剖面二维土壤水运移模型，该模型的优势在于可灵活地处理下边界和上边界条件，试验场观测数据拟合表明模型精度较高，可用于研究各种条件下土壤蒸发、土壤水分下渗补给地下水等问题。
