When we try to estimate the evapotranspiration from a complex land-use surface under the condition that the records of hydrological data observed are available for only limited locations, we must use some technique to average each evapotranspiration from the single land-use surface. Even if we use the remote sensing the observation near the surface and the technique to average may be needed for the surface truth.In this study numerical simulation is undertaken. The model is 2-dimensional so that the effect of advection can be described. In this model not only atmosphere but also underground region is described in detail. And, the technique to average over the area is discussed.As a result, some basic knowledge about the averaging technique is given.Evapotranspiration from single land-use surface is estimated at the center of that area. Furthermore, as for the evapotranspiration from the complex land-use surface, it can be estimated by each evapotranspiration at the center and each area occupied.
