Dr. M. Rajabi[1], K. khoshdel[2] Abstract The study area is Ahrchay upstream basin. Because of the mountainous region is a sensitive area in terms of erosion. Most parts of the basin, are permanent. When Ahrchay branches arrive the flat area, the river meanders be converted. Ozomdel Varzeghan Plain, as a result of blockage by volcanic activity has occurred near the village of Sghendel. Digging trenches and sediments of the seabed by Ahrchay cause appears to have been made. In spring and late winter rainfall and melting snow caused river flooding is causing erosion and transportation of sediments found there by the river. In areas where the slope is to slow the stream sediment deposition. The material in foothill and lowland areas has formed alluvial terraces. In this study the geomorphic characteristics of the terrace deposits is investigated. For this study, 15 out of deposits terraces for grain harvested. Charts on different parameters such as (MD), (MZ), (QI), (SKG) and (SKI) is extracted and were analyzed separately. Grading of terraces and other characteristics of sediments show also features river terrace. 1 Professor of Geomorphology, University of Tabriz mrajabi@tabrizu.ac.ir 2 Geomorphology Ph.D. student, University of Tabriz Khoshdel8@tabrizu.ac.ir
