Evaporation from water‐surfaces: Status of present knowledge and need for further investigations

Abstract

Five different methods have been proposed for estimating evaporation from lakes. These are: (1) The atmometer; (2) various designs of pan; (3) empirical equations embodying functions of wind, humidity, air‐temperature, and water‐temperature; (4) air‐temperature alone; and (5) the following equations based on thermodynamics and molecular theory:
