Abstract:

Drought is an important event affecting the economic structure, sociocultural characteristics and ecological structure of a society. As a result of droughts dangerous situations are inevitable such as; drying of rivers and stream beds or damage to their flows, increased pressure on plants, decreased agricultural productivity and natural life activities, increased migration. It is possible to minimize these negative effects with certain size estimates of the drought. There are many methods used to describe the spatial and temporal characteristics and severity of drought. The most preferred of these methods is the "Standardized Precipitation Index (SPI). In the study, drought analysis was made for Salda Lake Basin using the Standardized Precipitation Index method. SPI values were calculated according to the data of Yesilova meteorology station in “1-3-6-12-24” month time periods. According to the results of the analysis, the most severe and longest droughts were observed between "1989-1995". When the droughts experienced in the last 10 years are evaluated, it is predicted that there may always be a drought close to normal in the area.
