This paper presents on a new method for estimating of daily evapotranspiration from mountainous river basin.
First, the actual daily evapotranspiration is estimated by using the observed daily evaporation at a mountainous site. Then, the Hamon's formula under the daily rainfall conditions is presented, and the parameters of the formula are calibrated by the estimated daily evapotranspiration. Finally, the expression is applied to two mountainous river basins, and a validity of the method for estimating the actual daily evapotranspiration and a practical utilization of the improved expression are discussed.
