Evaluation of Monthly Precipitation Amount in Eastern Anatolia Region by Using Trend Analysis Methods

Abstract


In this study, the research of trend analysis of total monthly and annual rainfalls fall to East Anatolia Region have been targeted. For this purpose, with applying Run test and Pettitt test to data that is taken from General Directorate of Meteorology’s 46 units rainfall observation station, changing from 1960 to 2013, homogeneity analysis was performed. With performing Mann-Kendall test and Spearman’s Rho test to station determined as homogeneous trend analysis was examined, with using Sen’s slope method trend’s slope was determined.

As to assessed monthly total rainfalls trend analysis, it is observed that in the summer months generally rainfalls are increasing direction tendency, in the winter months it is decreasing direction tendency. In summer in June when a decreasing direction tendency is dominated at region, in July it gives place to increasing direction tendency. When it is November, again decreasing direction tendency at monthly total rainfalls to region is dominated.
