Evaluation of Sediment Transport Rate in Coarse-Bed Rivers
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 (i.e. bed, suspended and total loads) from different methods. Three river reaches were selected as representatives of coarse-bed rivers in North-West of Iran, where observed data were available. A sediment transport model (STM-CBR) 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 prediction results and the order of errors for different modes of the sediment loads under different flow conditions. With the inclusion of the order of predictive errors, the best-fitted relationships are recommended for the proper evaluation of different modes of sediment loads in similar coarse-bed river reaches.
