Overview

The Evapotranspiration advanced course aims to introduce the concept of evapotranspiration, determine the factors affecting evapotranspiration. This course also describes methods for estimating the rate of evapotranspiration. Through the study of this course, the mechanism of the evapotranspiration process and the importance of evapotranspiration estimation in agricultural planning are discussed. using remote sensing techniques in estimating actual and potential evapotranspiration and estimating the expected crop yield.

Intended learning outcomes

By the end of the course the student will be able to:
