Several drought indices were carried out to determine drought. By means of these indices, drought can be determined and necessary precautions can be taken against drought. In this study, an annual drought survey was conducted using the rainfall records of the Boyabat meteorological observation station in the Kizilirmak River Basin in the 1976-2017. In the drought analysis, the meteorological drought indices Z-Score Index, China-Z Index and Modified China-Z Index were used. The dry and wet periods of the station were determined by means of meteorological drought indices, and the driest and wettest years were also determined. In the study, which also examined the compatibility between indices, it was determined that the coefficient of determination values of MCZI-ZSI and MCZI-CZI were higher than the ZSI-CZI. Drought events in Boyabat region should be investigated using different indices.Etkilerini her geçen gün artiran bir dogal afet olan kuraklik, önemli zararlar verebilmektedir. Kurakligi belirlemek için çesitli kuraklik indeksleri yapilmistir. Bu endeksler sayesinde kuraklik belirlenebilir ve kurakliga karsi gerekli önlemler alinabilir. Bu çalismada, Kizilirmak Havzasinda Boyabat meteorolojik gözlem istasyonuna ait 1976-2017 yagis kayitlari kullanilarak yillik kuraklik arastirmasi yapilmistir. Kuraklik analizinde meteorolojik kuraklik endeksleri olan Z-Score Index, China-Z Index ve Modified China-Z Index kullanilmistir. Istasyonun kurak ve yagisli dönemleri meteorolojik kuraklik indeksleri araciligiyla belirlenmis, ayrica en kurak ve en yagisli yillar da belirlenmistir. Endeksler arasi uyumun da incelendigi çalismada, MCZI-ZSI ve MCZI-CZI korelasyon katsayisi ZSI-CZI’ye göre daha yüksek oldugu belirlendi. Boyabat bölgesindeki kuraklik olaylari farkli endeksler kullanilarak arastirilmalidir.eninfo:eu-repo/semantics/openAccessDroughtDrought MonitoringDrought IndicesBoyabatArticle518Jan10.51764/smutgd.993652https://doi.org/10.51764/smutgd.993652
