Abstract

The value of water evaporation is a key data in establishing the water balance of lakes and reservoir dams. In general, the evaporation of water bodies is assessed either from observation data from evaporation pan (Colorado pan and class A pan), or by analogy with other reservoir dams for which these data are available. In frequent cases, the evaluation of the evaporation of water bodies becomes impossible by applying the two methods mentioned because of the reduced number of weather stations or the absence of evaporation pans among their equipment. Applying the analogy with other reservoir dams, it can lead to considerable errors. In order to eliminate the difficulty of determining the evaporation of water, often encountered by engineers and operators of reservoir dams, the development of a calculation method simulating the phenomenon of evaporation is essential.
