description Drought is a major problem faced by the entire ecosystem on a global scale. Hydrological drought occurs because of the dangerous depletion of water resources, an indispensable aspect for the continuation of life. The Akarçay Closed Basin, where meteorological drought is commonly observed, is home to important wetlands. Recently, the pressure on the wetlands of this basin has increased because of climate change and poor water resource management policies, which has led to the deterioration of the basin water budget and spatial changes in the wetlands. This study examined the traces of hydrological drought in the Akarçay Closed Basin using the streamflow drought index (SDI). The SDI was calculated for four different reference periods using the time series consisting of 45 years of flow data. The possible trends on the flow series were investigated using the Mann–Kendall test and the Mann–Kendall rank correlation test statistics for a better interpretation of the SDI. Traces of hydrological drought were detected at selected stations in the Akarçay Closed Basin (SDI<0). A significant negative trend was found in the flow data starting on different dates during different reference periods. The magnitude and duration of hydrological drought have increased since the mid-1980s.
