An Evaluation of the Causes and Consequences of the Flash Floods (5.9.2023) in the Degirmen River Basin in Igneada (Demirkoy/Kırklareli)

Öz

On 5.9.2023, flash floods occurred in Igneada town of Demirkoy district of Kırklareli province, which caused serious loss of life and property. Since this unfortunate event was a natural hazard with a hydro-meteorological characteristic, it occurred at the river basin scale. Therefore, the present study aims to systematically reveal the chain of events leading to the flash floods in the Degirmen River basin, where the natural hazard occurred. The study data were processed and interpreted in the light of the relevant literature within the framework of the findings obtained from office and field studies. At this stage, the Root Cause Analysis (RCA) method was used to determine how and why the event occurred and how to prevent similar problems from occurring again. As a result of the study, it was determined that flash floods caused by sudden torrential rains led to high-energy water flows on the slope lands depending on topographic features. Consequently, they forced the transportation of materials of various sizes. The materials coming from the river's upper basin with strong flash floods with irregularly changing flow rates triggered flooding in places where the slope of the river bed decreased. However, this natural event has become a natural hazard in the lower basin due to the wrong land use caused by the negative anthropogenic effects of human beings on the natural environment.

İğneada (Demirköy/Kırklareli) Değirmen Deresi Havzasında Meydana Gelen Selin (5.9.2023) Nedenleri ve Sonuçları Üzerine Bir Değerlendirme

Öz

5.9.2023 tarihinde Kırklareli ilinin Demirköy ilçesine bağlı İğneada beldesinde ciddi can ve mal kaybına neden olan bir sel meydana gelmiştir. Bu elim olay hidro-meteorolojik karakterli bir doğal afet olduğu için akarsu havzası ölçeğinde meydana gelmiştir. Bu nedenle, bu çalışma doğal afetin meydana geldiği Değirmen dere havzasında sele yol açan olaylar zincirini sistematik olarak ortaya koymayı amaçlamaktadır. Çalışma verileri, ofis ve saha çalışmalarından elde edilen bulgular çerçevesinde ilgili literatür ışığında işlenmiş ve yorumlanmıştır. Bu aşamada olayın nasıl ve neden meydana geldiğini saptamak ve benzer problemlerin tekrar yaşanmasının nasıl önlenebileceğini tespit etmek için Kök Neden Analizi (KNA) yöntemi kullanılmıştır. Çalışma sonucunda aniden gelişen sağanak yağışların sebep olduğu sel olayının, topografik özelliklere bağlı olarak yamaç arazilerde yüksek enerjili su akımlarına ve buna bağlı olarak çok değişik boyutlardaki malzemenin taşınmasına sebep olduğu tespit edilmiştir. Akarsuyun üst havzasından debisi çok düzensiz bir şekilde değişen güçlü sel suları ile gelen malzemeler akarsu yatağında eğimin azaldığı yerlerde su baskınlarının yaşanmasını tetiklemiştir. Ancak bu doğal olay, özellikle insanın doğal ortam üzerindeki olumsuz antropojenik etkilerinin yol açtığı yanlış arazi kullanımıyla alt havzada afet karakteri kazanmıştır.
