ABSTRACT
In this paper, on basis of the exponential hydraulic parameter model proposed by Gardner (1958), an analytical solution is proposed by linearizing Richards’ equation to model soil water dynamic
1 INTRODUCTION
Evaporation is an important process in earth’s hydrological cycle that whereby liquid water undergoes a change of state and is converted into vapor. It is critical for various engineering, environmental and hydrological applications such as water evaporation from land surface and its application in hydrological modeling (Shokri and Or, 2011), solution accumulation near earth surface, performance of soil cover (Wilson, 1994; Yanful and Mousavi, 2003), and so on. Moreover, the dynamic of soil water content during evaporation is required for the assessment of soil water management practices (Blight, 1997; Cui et al., 2005; Cui and Zornberg, 2008; Fredlund et al., 2010).
