Ergene Havzası'nda Kuraklık Riskinin Değerlendirilmesi

Abstract

Bölgesel ölçekte değerlendirildiğinde, Türkiye coğrafi konumu nedeniyle hassas bir bölgede yer almaktadır ve bölgenin topografyası kuraklığa karşı savunmasızdır. Araştırma alanı olan Ergene Havzası, son yıllarda kuraklık riskiyle karşı karşıyadır. Bu nedenle, kuraklığın olası başlangıç zamanını belirlemek ve olası etkilerini ve süresini araştırmak havza için kritik öneme sahiptir. Bu çalışma, Ergene Havzası'nın iklim özelliklerini belirlemeyi ve kuraklık potansiyelini değerlendirmeyi amaçlamaktadır. İklim özelliklerini incelemek için Thornthwaite İklim Sınıflandırması ve Mann Kendal testi kullanılırken, kuraklık potansiyelini incelemek için Standartlaştırılmış Yağış İndisi yöntemi kullanılmıştır. Gerçekten de havzanın yarı kurak-düşük nemli ve yarı nemli iklim sınıflandırmasına girdiğini anlaşılmıştır. Kuraklık analizleri, havzanın kuzeyden güneye doğru artan bir kuraklık eğilimi gösterdiğini ortaya koymuştur.

Assessment of Drought Risk in the Ergene Basin

Abstract

On a regional scale, Turkey is located in a sensitive area because of its geographical position, and the region's topography makes it vulnerable to drought. The Ergene Basin, which is the research area, has been at risk of drought in recent years. Therefore, determining the potential onset time of drought and researching its possible effects and duration are of critical importance for the basin. This study aims to characterize the climate of the Ergene Basin and to assess its drought potential. The Thornthwaite climate classification and the Mann-Kendall test were used to examine climatic characteristics, while the Standardised Precipitation Index was used to examine drought potential. The basin falls under the semi-arid (low-humidity) and semi-humid climate classifications. Drought analyses have revealed that the basin exhibits a trend of increasing aridity from north to south.
