Overall, our object has been to provide an applications-oriented text that is reasonably self-
contained. It has been used as the basis for a graduate-level course both at the University of …

In this chapter we describe the development of in situ techniques to measure the hydraulic
properties of the soil surface and to assess quantitatively the contributions of preferential …

Vadose zone hydrology has received increased attention in recent years as a result of
environmental concerns over potential groundwater pollution from buried wastes. Funding …

This work develops a simple exact and explicit solution of the one-dimensional transient and
nonlinear Richards' equation for soils in a special case of exponential water retention curve …

Analytical solutions are developed for the Richards' equation following the analysis of
Broadbridge and White. Included here is the solution for drainage and redistribution of a …

An analytical solution is developed for Richards equation for time‐varying infiltration. The
infiltration rates must be specified as piecewise constants with time. The answer is …

Infiltration systems are widely used as an effective urban stormwater control measure. Most
design methods and models roughly approximate the complex physical flow processes in …

An exhaustive classical symmetry analysis is carried out for the general class of nonlinear
diffusion-convection equations in (1+ 1) dimensions, and the corresponding optimal system …

A non-linear diffusion model of Fujita is adapted to obtain an analytic solution describing the
temperature distribution and position of any number of phase boundaries as a material cools …

基于可控的坡面间歇降雨和多场次降雨试验, 对黄土坡面土壤水分入渗及分布特征进行了研究.
结果表明: 间歇降雨条件下, 两次降雨期间的累积径流量均随降雨历时的延长呈近似线性增加 …
