A Research on Sinuosity of Ahar Chay Meanders in Ozomdel Plain, Yarzeghan, East Azerbaijan, Iran

Ozomdel plain was located in Varzeghan county of East Azerbaijan. This plain is the only plain in Varzeghan at the north of the city. Ahar Chay is flowing from the south of city.

The river in the study area has been developed meander form because of lowering the slope in the plain. Most of meanders are stable. The aim of this study is indicating of developing of Ahar Chay river by quantitative methods. For this aim, Kornise Index and sinuosity ratio are used. Meanders of Ozomdel plain are developed on the base of Indexes.
