Abstract:

 Earthquakes can cause topographic changes and increase the flood risk by changing the river channel structure and route. Pazarcık and Elbistan earthquakes on February 6, 2023 are also flood-triggering earthquakes. Numerical solutions were carried out with HEC-RAS software for the flood effects of these earthquakes. The study area is the Sarsap train station area in Malatya province. A bridge structure was modeled over Eskiköprü Stream Kuruçay to provide an uninterrupted connection from the station to the highway after the earthquake. Flood recurrence flows were calculated using the Dsi Synthetic Method. Manning roughness coefficient was found according to Modified Cowan Method. Solutions were taken for 33 sections according to the 100-year flood flow. As a result, water surface profiles were obtained in all sections and the flow easily passed through all sections, including the bridge section. It can said that this study will form an important basis for post-earthquake rehabilitation studies.

 Depremler topografik değişikliklere neden olup, akarsu kanal yapısını ve güzergahını değiştirerek taşkın riskini arttırabilir. 6 Şubat 2023 teki Pazarcık ve Elbistan depremleri de taşkını tetikleyici depremlerdir. Bu depremlerin taşkına etkisi için, HEC-RAS yazılımı ile sayısal çözümler gerçekleştirilmiştir. Çalışma alanı Malatya ilindeki Sarsap tren istasyonu bölgesidir. Deprem sonrası istasyondan, karayolu ile kesintisiz bir bağlantı sağlamak için Eskiköprü Çayı Kuruçay üzerinde bir köprü yapısı modellenmiştir. Dsi Sentetik Yöntem kullanılarak taşkın tekerrür debileri hesaplanmıştır. Modifiye Cowan Metoduna göre Manning pürüzlülük katsayısı bulunmuştur. 100 yıllık taşkın debisine göre 33 kesitte çözümler alınmıştır. Sonuçta bütün kesitlerde su yüzeyi profilleri elde edilmiş ve köprü kesiti de dahil akım bütün kesitlerden rahatlıkla geçmiştir. Bu çalışmanın deprem sonrası rehabilitasyon çalışmalarında önemli bir altlık oluşturacağı söylenebilir.
