Hydrological Drought Analysis of Asi River Basin with Streamflow Drought Index
Abstract
In this study, hydrological drought analysis is carried out by using 52 years (1954-2005) streamflow data of Asi River Basin in the south of Turkey. Streamflow Drought Index (SDI) method is used in determining the drought. The severity, the size and the distribution according to the drought and wet period of Asi River Basin were determined for 3, 6 and 12-month time scales by using monthly streamflow data. As a result, drought year in the period of 1979-2005 are observed more according to the period of 1954-1979. The extreme droughts are determined in the year of 2000 and 2001 for the all-time scales.
