Abstract

In this study, stage-discharge relationships in compound channels and reliability and performance of COH (Coherence) Method were investigated. Discharge measurements for overbank flow were conducted in a two stage straight channel flume with various water depths and roughnesses. COH method developed by Ackers (1991) for the trapezoidal cross-sectional compound channels was applied to all the experimental data obtained from the rectangular cross-sectional compound channels and these results were compared. It was observed that COH method predicts the stage-discharge relationships well for two-stage channels, which have smooth and rough floodplains.

Özet

Bu çalışmada bileşik kesitli yataklardaki seviye-debi ilişkisi deneysel olarak irdelenmiş ve bu ilişkiyi matematiksel olarak hesaplayan COH (Coherence) yönteminin uygulanabilirliği araştırılmıştır. Taşkın durumundaki akım hali için, debi ölçümleri, farklı su derinlikleri ve pürüzlülük için iki seviyeli deneysel bir düzenek üzerinde yapılmıştır. Ackers (1991) tarafından, trapez kanallar üzerindeki deneysel verilerin kullanılması ile geliştirilen COH yön-temi, bu çalışmada diktdörtgen kesitli kanaldaki tüm deneysel verilere uygulanarak, elde edilen sonuçlar karşılaştırılmıştır. Pürüzlü ve pürüzsüz taşkın yataklarına sahip iki seviyeli düz bir yatak için, COH yönteminin seviye-debi ilişkisini oldukça iyi hesap edebildiği gözlenmiştir.
