Abstract:
The process of flow and sediment transport is different and more complex in coarse-bed rivers than in sand-bed rivers. The main aim of the present study was to evaluate different modes of sediment transport, from different methods. Three river reaches were selected as representatives of coarse-bed rivers in Northwest of Iran. A sediment transport model (STM) was developed to calculate the bed loads from 13 methods, the suspended loads from 4 methods and the total loads from 10 methods. The effects of bed material characteristics were also examined. This paper presents the order of uncertainties for the prediction of different modes of sediment transport in similar coarse-bed river reaches
