The Trend Analysis of Lakes Region Precipitation Data in Turkey
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 1
Abstract
In recent years, population growth, urbanization, tainted water use policies, water pollution due to industrialization and climate change has led to the re-evaluation of water resources. Because the protection plans developed in the past have lost their validity, the new prevention plans made today have caused to the critical analysis. In this research, the monthly precipitation data was analyzed for Lakes Region located in the Middle Mediterranean Regionin Turkey. For this purpose, the data were subjected to homogeneity test, and the Mann Kendall test, the Sen’s test and the lineer regression for trend analysis were applied to data. The analyses for historical monthly precipitation records were made to nine meteorological stations which identified in the study area:the Ağlasun, Barla, Aksu, Bucak, Yalvaç, Sütçüler, Kızılkaya, Kasımlar, and Gelendost stations. Also, 3, 6, 9, 12 monthly Standardized Precipitation Index (SPI) values of these stations were examined by using the Mann Kendall test, Sen’s test and lineer regression to support historical trend analysis. According to the results of the tests, a decreasing trend has been observed in most of the nine stations.
