The purpose of this paper is to develop a model for estimating evapo-transpiration over a wide area covered by forest using vegetation index which closely relates to evapotranspiration. The distribution of NDVI (Normalized Differences Vegetation Index) calculated from NOAA-AVHRR data is compared with the total evapotranspiration evaluated by the conventional method (Thornthwaite method). Using one year data set in the Okutadami basin mainly covered with deciduous trees, correlation between evapotranspiration and NDVI is derived with muliple regression analysis. It is concluded that evapotranspiration in a decidous forest is propotional to NDVI. The distribution of evapotranspiration in the basin can be estimated from the correlation.
