Abstract

Bu çalışmada, bileşik kesitli kanallarda debi hesaplamasında ikincil akımların etkisi Shiono-Knight Metodu (SKM) ile araştırılmıştır. Literatürde yayınlanmış ve laboratuar ortamında ölçülmüş debiler SKM kullanılarak hesap edilmiştir. İkincil akımların etkisi, hesaplanan ve gözlenmiş debiler arasındaki ortalama mutlak rölatif hataya bakılarak belirlenmiştir. İkincil akımların debi hesaplamasında etkisinin olduğu ve rölatif derinlik arttıkça bu etkinin azaldığı görülmüştür.

The Effect Of Secondary Flows In Compound Channels

Abstract

In this study, the effect of secondary flows on the conveyance capacity of the compound channels was investigated by Shiono-Knight Method (SKM). Discharges, which were observed and published in the literature, were calculated using SKM. The effect of secondary flows was determined with the mean absolute relative error between observed and computed discharges. It was determined that the secondary flows have an effect on the calculation of the conveyance capacity, and this effect decreases with an increase in relative depth.
