Calculation of losses for transpiration in water reservoirs with using new computer technologies

Reservoirs are important object for the agriculture and national economy of Uzbekistan. In this article provided hydraulic and hydrological calculations of loss in water reservoirs with using new methodologies and computer technologies. Novelty of the research is modernizing calculation method. With this gotten high accuracy data. In calculations of los for transpiration in other researches counts only transpiration of water surface. With using CropWat model it is possible to calculate evaporation and transpiration.
