Abstract
Drought, which is a natural disaster that increases its effects day by day, can cause significant damage. 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.
