Abstract:
The purpose of this study is to estimate the steady state evaporation rates from layered
soils in the presence of high water table under isothermal conditions. A finite difference numerical
scheme based upon the one-dimensional Richards equation has been employed to
estimate the evaporation rates from a two-layered soil profile overlying a shallow water for
appropriate initial and boundary conditions. The method takes into account the relevant atmospheric
factors and soil moisture characteristics of the two layers. The effects of sequence
and thickness of the soil layers and water table depth on the evaporation rates have been
examined.
