Analysis of Evaluation Stages Involved in Penman Monteith Equation

Abstract

Evapotranspiration plays pivotal role in water management schemes and irrigation scheduling design. Water resource engineers and strategic planners are therefore highly focusing on finding out more accurate methods for its measurement. Several scientists have formulated many formulae for predicting this very important parameter but all these methods have shortfalls. To resolve the ambiguity of choice United Nations and American Society of Civil Engineers accepted the Penman Monteith equation accepted for measurement for reference evapotranspiration to come to a consensus. Here, we have provided the steps involved for effective measurement of evapotranspiration. The article is divided into five sections. Section One introduces the essence and importance of Evapotranspiration. Section Two speaks about the climatic parameters that require measurement. Section Three discusses the very important Penman – Monteith equation. Section Four elaborates on the stages those are involved for efficient measurement of this equation followed by a brief conclusion in Section Five.
