Abstract

Sunulan çalışmada, aylık yağış-akış ilişkisini tanımlamak amacıyla Budyko yaklaşımına dayanan dinamik su bütçesi modeli kullanılmıştır. Önerilen 5 parametreli model girdi olarak sadece aylık alansal ortalama yağış ve potansiyel evapotranspirasyon verilerine ihtiyaç duymaktadır. Çalışma sahası Gediz Havzası’ndaki Medar Çayı’nı kapsamaktadır. Modelin performansını sınamak maksadıyla farklı ölçütler değerlendirilmiştir. Çalışmadan elde edilen bulgular, dinamik su bütçesi modelinin aylık akış serilerini modellemede başarılı olduğunu göstermiştir

Dynamic Water Budget Model

Abstract

In the study presented, to define monthly rainfall-runoff relation, dynamic water budget model based on Budyko approach was used. Proposed model having 5- parameter requires only monthly areal precipitation and potential evapotranspiration data as input. The study region covers the Medar River which is located at the Gediz Basin. To validate the model performance, different measures were assessed. The results derived from the study show that dynamic water budget model is successful in modeling of monthly runoff series
