Effect on the regional climate of Keban dam lake for energy studies of elazığ province

In this study, the effect of Keban Dam Lake on Elazığ climate was revealed. The assessed data that measured and observed are meteorological data between 1938 and 2015. Analysis of the data was conducted, and the results were presented in tables and figures. The climatic characteristics of Elazığ have been revealed by considering most of the climate parameters. It is known that the major changes in the surface area of a region affect the climate of its immediate surroundings. Dam lakes are also large structures in terms of area they cover. Climate characteristics of the pre-dam (1938-1974) and post-dam (1975-2015) periods were revealed with the aim of determining the impact of the dam lake to the Elazığ climate. It has been determined that there are some changes in meteorological data between the pre-dam and post-dam periods. These changes were compared with meteorological data both in Turkey and the Euphrates-Tigris basin. According to the obtained results, although Keban Dam Lake did not make any significant changes in Elazığ climate, some changes were observed in meteorological data. It is observed that there is a decrease trend in precipitation and rising trend in relative humidity and temperature. Keywords: Elazığ, Energy, Effect of Dam Lake to Climate
