Özet:

In recent years, especially in accordance with the EU Water Framework Directive, taking into account the implementation of water management based on the pool, the DSI Regional Directorate has started accounting work with the current data for the 25 main pool of the water budget. For this purpose, the current value measurements are carried out for 25 flow pools in the current measurement stations operated by the Electrical Affairs Research Administration. However, according to some climate analysis methods, water potential can also be predicted. In this study, a total of 278 meteorological stations in Turkey data, according to the Thornthwaite method, the climate analysis has determined the water potential of Turkey. In the study, a different approach was used to determine the water potential of Turkey. In the framework of the study, the data calculated for the 25 flow pools in Turkey (the rain, the GET and the excess of water) and the differences between the flow values of the flow in each pools have been revealed. According to the measurements made in 1980, 2000 and 2012, the amount of water in Turkey is an average of 181.49 billion m3. In this study, the water potential of Turkey was calculated as 180,66 billion m3 according to the Thornthwaite method.
