Özet:

In this study, Göynük Stream Basin, one of the important river basins of Bingöl Province, has been determined as the study area. By analyzing hydrological (current) and climatological (temperature, precipitation) data of the basin, the trends and correlations with each other were tried to be explained. For this purpose, hydroclimatological data series covering the 47-year period between 1970-2017 were provided. Three different statistical techniques, homogeneity test, trend test and correlation tests were applied to each of the data series obtained. Linear trend analysis and Mann-Kendal test were used to determine the direction distribution and amount of trends. In addition, Kendall tau and Spearman rho tests were applied to determine the correlations of the variables with each other. According to the results of the analysis, the average temperature values of the Bingöl Meteorology Station for the period between 1970-2017 tend to increase and the total precipitation values tend to decrease. A decreasing trend was observed in the current values of Göynük Stream Çayağzı Station. In addition, while there is a positive and linear relationship between precipitation and current, there is a negative and inverse proportional relationship between temperature-precipitation and temperature-current.
