Abstract

The increasing importance of water resources planning and management each day has led to a widespread use of hydrologic modeling. Especially in Turkey, where the headwaters of drainage basins are located around mountainous areas, snowmelt dominates streamflow during spring months which makes modeling applications important and necessary. In this study, two different conceptual hydrologic models (HEC-HMS and HBV) are compared during 2008-2015 water years in the mountainous headwaters of Aras Basin, located in eastern Turkey. For both models, performance on runoff using Nash-Sutcliffe Efficiency is above 0.8 and 0.7 for calibration and validation respectively. This first conceptual hydrologic modeling implementation and comparison in Aras Basin did indeed give promising results as well as suggesting to consider other variables beside streamflow.

Özet

Günbegün önemi artan su kaynakları planlama ve yönetimiçalışmalarında hidrolojik modellemenin etkin kullanılmasıyaygınlaşmaktadır. Özellikle Türkiye’deki drenaj havzaları başlangıçbölgelerinin karlı dağlık alanlardan oluşması ve bahar aylarındakarların erimesiyle birlikte akımların büyük bir bölümünün karerimesinden meydana gelmesi bu bölgelerdeki modellemeuygulamalarını önemli ve zorunlu kılmaktadır. Bu çalışmada,Türkiye’nin doğu ve dağlık bölgesinde yer alan Aras Havzasınınmemba suları iki farklı kavramsal hidrolojik model (HEC-HMS ve HBV)kullanılarak 2008-2015 su yılları arasında modellenmiş vekarşılaştırılmıştır. Nash-Sutcliffe ölçütü kullanılarak performansıdeğerlendirilen her iki modelin akıma göre kalibrasyon başarısı 0.8 vedoğrulaması 0.7 değerlerinin üzerinde bulunmuştur. Aras Havzasındaöncül bir kavramsal hidrolojik modelleme uygulaması olan bukarşılaştırma çalışmasının başarılı sayılabilecek sonuçlar verdiği vebenzer çalışmaların akımın yanı sıra başka değişkenlerin de çalışmayadahil edilebileceğini göstermiştir.
