Abstract:

 Identifying meteorological droughts, which occur as a result of precipitation falling below long-term averages, plays a vital role in the sustainable management of water resources. The characteristic features of the drought process, such as duration, severity and intensity, which begin with meteorological drought, also affect the formation and characteristics of hydrological and agricultural droughts. Therefore, index-based methods characterize meteorological drought processes by utilizing factors like precipitation, temperature, and potential evapotranspiration. In the study conducted for Bartın province, located within the Western Black Sea Basin, meteorological droughts were examined in 1, 3, 6 and 12-month time scales between 1970 and 2020. The identification of meteorological droughts was performed using three standardized indices: the Standardized Precipitation Index SPI, the Standardized Precipitation Evapotranspiration Index SPEI, and the Standardized Precipitation Temperature Index SPTI. The analysis revealed that, across different temporal scales, all drought severity classes were observed. Furthermore, the long-term 12-month drought characteristics were assessed using Run Theory, identifying the most severe dry period as occurring between 1981 and 1982.

 Yağışların uzun dönem ortalamalarının altında kalmasıyla meydana gelen meteorolojik kuraklıkların belirlenmesi, su kaynaklarının sürdürülebilir yönetiminde önemli bir rol oynar. Meteorolojik kuraklık, süresi, şiddeti ve yoğunluğu gibi özellikleriyle hidrolojik ve tarımsal kuraklıkların oluşumunu ve niteliklerini doğrudan etkiler. Bu süreçlerin açıklanmasında kullanılan indis yöntemleri, yağış miktarı, sıcaklık ve potansiyel evapotranspirasyon gibi faktörlere dayalı olarak meteorolojik kuraklık olaylarını tanımlar. Batı Karadeniz Havzasında yer alan Bartın ili için 1970-2020 yılları arasında 1, 3, 6 ve 12 aylık dönemlerde meteorolojik kuraklıklar incelenmiştir. Meteorolojik kuraklıkların tespitinde Standartlaştırılmış Yağış İndisi SPI, Standartlaştırılmış Yağış ve Evapotranspirasyon İndisi SPEI ve Standartlaştırılmış Yağış ve Sıcaklık İndisi SPTI yöntemleri kullanılmıştır. Üç farklı standardize indis yöntemiyle yapılan analizlerde, farklı zaman dilimlerinde tüm kuraklık sınıflarının gözlemlendiği tespit edilmiştir. Çalışmada, uzun dönemli 12 aylık kuraklıkların karakteristik özellikleri Run gidişler teorisi ile değerlendirilmiş ve en şiddetli kuraklık döneminin 1981-1982 yılları arasında gerçekleştiği belirlenmiştir.
