Modeling of Evaporation from Bare Land including advection and ground water flow

Abstract

For estimation of evaporation rate from large area including a lot of fields which have different characters, for example roughness and wetness, the way how to average evaporation in each fields must be known. In order to estimate the effect of difference of ground surface, the effects of advection and development of internal boundary layer must be investigated.
In this paper, a numerical simulation by a two-dimensional model has been undertaken. In this model, the advection in atmosphere and the ground water flow are included. And some results by this simulation model have been given.
