Abstract

Low, medium and high values of a variable are a significant issue in hydrological, meteorological and climatological events; moreover, these values are used to decide various design parameters based on scientific aspects and real applications around the world. In this context, a new trend method recently proposed by Şen was used for monthly streamflow data recorded at two different stations (2174- Murat River (Akkonak) and 2634-Garzan Creek (Kozluk)) in Euphrates-Tigris Basin. The Mann-Kendall trend test was also applied to the same data. It was seen that the stations had statistically significant decreasing trend according to the Mann-Kendall and Şen trend test at 95% confidence level; moreover, the proposed method provided an important advantage in terms of graphically evaluation of low, medium and high values of streamflow data.

Özet

Bir değişkenin düşük, orta ve yüksek değerleri hidrolojik, meteorolojik veiklimsel olaylarda önemli bir konudur. Ayrıca, bu değerler, dünyanın çeşitliyerlerindeki bilimsel yönlere ve gerçek uygulamalara dayanan çeşitli tasarımparametrelerini belirlemek için kullanılır. Bu bağlamda, Fırat-Dicle Havzasında ikifarklı istasyonda (2174-Murat Nehri (Akkonak) ve 2634-Garzan Çayı (Kozluk))kaydedilen aylık akarsu verileri için yakın zamanda Şen tarafından önerilen yenibir eğilim yöntemi kullanılmıştır. Aynı verilere Mann-Kendall eğilim testi deuygulandı. İstasyonların, Mann-Kendall ve Şen eğilim testine göre istatistikselolarak %95 güven düzeyinde önemli düşüş eğilimi gösterdİ. Önerilen yöntem, akışakışı verisinin düşük, orta ve yüksek değerlerinin grafik olarak değerlendirilmesiaçısından önemli bir avantaj sağladı.
