Conference Object Citation - WoS: 2Evaluation of Streamflow Drought Index in Aegean Region- Turkey(SPRINGER INTERNATIONAL PUBLISHING AG, 2022) Ayse Gulmez; Denizhan Mersin; Babak Vaheddoost; Mir Jafar Sadegh Safari; Vaheddoost, Babak; Safari, Mir Jafar Sadegh; Mersin, Denizhan; Gulmez, Ayse; H Gokcekus; Y KassemWater is an invaluable substance of which ensures the life cycle and hydrological events across the world. In this respect water deficit also known as drought is a natural disaster related to water scarcity in time and space. Although there is no solid definition for the phenomenon the outcome of repeated wet and dry spells cause in economic social and political problems at regional country-wide and world-wide scale. In this study drought associated with the streamflow in the Aegean region which has an important economic historical and wsocio-cultural role in the western Turkey is investigated through the well-known streamflow drought index (SDI). Therefore average discharge in the Cicekli-Nif Besdegirmenler-Dandalas Bebekler-Rahmanlar and Kocarli-Koprubasi station respectively related to on Gediz Buyuk Menderes and Kucuk Menderes basins were used. Then SDI with 1 3 612 months moving average are acquired to express the drought severity associated with the streamflow in the basins. Results showed that the SDI values in all of stations together with the 1 3 6 and 12-month moving averages depicts similar results and no abnormal situation exist during the study period.Article Citation - WoS: 9Citation - Scopus: 11A Joint Evaluation of Streamflow Drought and Standard Precipitation Indices in Aegean Region- Turkey(SPRINGER BASEL AG, 2023) Ayse Gulmez; Denizhan Mersin; Babak Vaheddoost; Mir Jafar Sadegh Safari; Gokmen Tayfur; Tayfur, Gokmen; Vaheddoost, Babak; Safari, Mir Jafar Sadegh; Mersin, Denizhan; Gulmez, AyseWater is an invaluable substance that ensures the life cycle and causes hydrologic events worldwide. Water deficit also known as drought is a naturally occurring disaster that affects the hydrometeorologic and/or climatic responses in time and space. In this study the meteorologic and hydrologic droughts in Buyuk Menderes Kucuk Menderes and Gediz basins in Turkey are investigated. The streamflow drought index (SDI) and standard precipitation index (SPI) are used considering different time windows. To achieve this the monthly streamflow at Cicekli-Nif Besdegirmenler-Dandalas Bebekler-Rahmanlar and Kocarli-Koprubasi hydrometric stations together with monthly precipitation at 14 meteorologic stations during 1973-2020 (47 years) are used. The SDI and SPI with 1 3 6 and 12 months moving average are then used to express the association between the meteorologic and hydrologic droughts in the basin. Results showed that the SDI depicts no abnormal situations while the SPI rates in the 1980s and 2010s indicated severe droughts. It was concluded that the inner parts of the basins are prone to frequent droughts and there is a concordance between SPI and SDI patterns at the basin level. However minor discrepancies between SPI and SDI do exist and probably originated from temporal delays and water abstraction.Article Citation - WoS: 37Citation - Scopus: 40Historical Trends Associated with Annual Temperature and Precipitation in Aegean Turkey Where Are We Heading?(MDPI, 2022) Denizhan Mersin; Gökmen Tayfur; Babak Vaheddoost; Mir Jafar Sadegh Safari; Tayfur, Gokmen; Vaheddoost, Babak; Safari, Mir Jafar Sadegh; Mersin, DenizhanThe trend analysis of annual temperature (daily average) and total precipitation has been conducted for 14 stations located in the Aegean Region Turkey. The Sen Spearman’s rho and Mann-Kendall test methods are used in the detection of the historical trends in the region. The Pettitt test is also implemented to find the significance of the trend while the Theil-Sen approach is applied to detect the change point(s) in the time series. Findings of the following study indicate that both precipitation and temperature time series in the selected stations depict statistically significant trends with increasing nature. The rate of increase in precipitation and temperature by the Theil-Sen test is found to be 4.2–7.9 mm/year and 0.20–0.35 °C/decade respectively. It is also found that the turn points of the temperature trends determined by the Pettitt test occurred in 1998 for all the stations. According to the results the magnitude of the extreme events would change in the future which may help in conceptualizing the framework and the resilience of the infrastructures against climate change. © 2022 Elsevier B.V.

In this regard the continuously changing climate regardless of its cause or effect pushes the limit of the water deficit through time and space. Izmir is a raising city in Turkey which owns various water resources including but not limited to seashores lakes river streams and groundwater aquifers. In this study the long-term precipitation and temperature records from 14 meteorological stations between 1973 and 2020 (for 47 years) are used to investigate the drought characteristics in Buyuk Menderes Kucuk Menderes and Gediz basins located in the Aegean region of Turkey. For this the Standardized Precipitation Index (SPI) and the Standardized Precipitation Evapotranspiration Index (SPEI) Percent of Normal (PNI) and the so-called Discrepancy Precipitation Index (DPI) are used with consideration to 1- 3- 6- and 12-month moving averages to investigate the drought patterns. Results showed that the monthly indices depict very similar results for the entire region. However in the 1980s and 2010s droughts were more severe than the rest of the historical records. When the moving average operator is implemented in the analysis (3- 6- and 12-month periods) neither SPI nor the SPEI showed the same results at any stations. It is illustrated that the periods of severe and normal drought have occurred in the past yet the indices that are obtained using average values are generally within the normal limits but extreme values (extremely arid or extremely wet) occurred occasionally. It is also concluded that although there is a similarity between the implemented indices the DPI and PNI depict the highest resemblance.Conference Object Assessment of Drought in Izmir District Using Standardized Precipitation Index(Springer Nature, 2025) Tayfur, Gokmen; Vaheddoost, Babak; Safari, Mir Jafar Sadegh; Mersin, Denizhan; Gulmez, Ayse
