Comparison of Different Methods Used in Determination of Irrigation Reservoir Capacity

Abstract

Usually development of dams and irrigation-drainage projects requires high investment cost. Because of financial limitations, consideration of optimization techniques for determination of reservoir capacity is clear. Determination of reservoir capacity by classical methods such as mass curve Ripple method and sequent peak algorithm, don’t consider all effective parameters in problem. In these methods reservoir capacity may be estimated with a higher than that of optimization methods. In this research comparison between classical and modern methods for calculating one dam capacity in East Azerbaijan named Yalgiz Agac has been done. Results showed that the dam capacity with Ripple method mass curve will be 13.1 hm3, with sequent peak algorithm will be 6.86 hm3 and with non-linear optimization will be 6.19 hm3

Keywords

• Reservoir management,Ripple method mass curve,sequent peak,non-linear optimization

Sulama Amaçlı Hazne Kapasitesinin Belirlenmesinde Çeşitli Yöntemlerin Karşılaştırılması

Öz

Genel olarak sulama, su temini ve drenaj projelerinin gerçekleştirilmesi için büyük yatırımlara gerek duyulmaktadır. Finans kaynakların yetersizliğinden su temini için yapılması planlanan hazne kapasitesinin belirlenmesinde optimizasyon tekniklerini kullanmak zorunlu olmaktadır. Hazne kapasitesinin belirlemesinde; Ripple yöntemi ve Ardışık Pik Analizleri olarak tanımlanan klasik yöntemler problemin bütün etkin parametrelerini ve boyutlarını dikkate almamaktadır. Böyle durumlarda hazne kapasitesi gereğinden çok büyük olarak hesaplanabilir. Bu çalışmada, Doğu Azerbaycan”da İran’ın kuzey batısında bulunan sulama amaçlı Yalkız Ağac barajının kapasitesi; klasik ve optimizasyon yöntemleriyle belirlenmiştir. Sonuçlara göre hazne kapasitesi Ripple yöntemi ile 13.1 hm3, Ardışık Pik Analizleri yöntemi ile 6.86 hm3ve Doğrusal Olmayan Optimizasyon yöntemi ile 6.19 hm3olarak hesaplanmıştır
