Abstract

This research was carried out within the scope of analyzing the temperature and precipitation values ​​observed in the Kızılırmak watershed of Turkey between 2002 - 2016 and spatial modeling using GIS. In the study, Mann-Kendall, Spearman's Rho and Sen's trend slope method tests were applied to the climate data. Data from 13 meteorological stations in the Kızılırmak watershed were used. The general average of monthly maximum temperatures varied between 23.5 and 26.4 oC for many years. The general average of monthly minimum temperatures for many years is -4.5 - 1.2 oC. The total precipitation average was between  377.5 - 644.8 mm. As a result of the trend analyzes made at the 95% confidence level in the research, it was determined that there was an increasing trend in Kastamonu and Sivas meteorological stations at maximum temperatures, and an increasing trend in Çankırı, Gemerek and Kastamonu stations at minimum temperature changes. It was observed that there was a significant change in total precipitation at Kastamonu and Nevşehir stations.
