Abstract
The effects of free and forced convection mechanisms on evaporation rates from open water bodies is examined. Examination of measurements from seven water bodies (from very small to tens of square kilometers) indicates that evaporation resulting from forced convection progresses at its theoretical value for a wide range of ambient conditions. On the other hand, free convection effects are sensitive to the windspeed and water surface to air temperature difference. Based on the analysis presented, a new evaporation equation is obtained.Keywords
