THE EFFECT OF GLOBAL CLIMATE CHANGE ON WEST ANATOLIA STREAMFLOWS

The continuity of life and the development of civilization are directly related to the correct and careful use of resources in the world. The 19th and 20th centuries are the centuries which involve greatest changes in the history of mankind. The industrial era has transformed its self-sufficient life units into global life units. This has resulted in faster consumption and contamination of common living resources. This phenomenon, called global climate change, has influence on the probability and quantity of the natural phenomenons such as precipitation and flow. The correct evaluation of the results of the global climate change has become more important in terms of planning. In this study, flow data in the temperate climate region of the Anatolian peninsula are examined. The effect of climate change on the Western Anatolian flow data was examined and the change in tendency in flow data was tried to be determined by using the daily flow data of 39 current observation stations during the period of 1936-2015. Three common methods for statistical analysis were used; Buishand test, Pettitt test and Standard Normal Homogeneity test. As a result, it was determined that Western Anatolia streamflow trends changed in the first half of 1980s.
