Validation of an Experimental Procedure to Determine Bedload Transport Rates in Steep Channels with Coarse Sediment

The current study presents an experimental procedure used to determine bedload sediment transport rates in channels with high gradients and coarse sediment. With the aim validate for further investigations, laboratory experiments were performed calculate rates. a tilting flume slopes ranging from 3% 5%. particles uniform shape (spheres). divided into four cases based on size. Three of sizes 10 mm, 15 mm 25 case grain size distribution formed particle considered. From results mathematical model was obtained through multiple linear regression. compared equations presented literature gravel bed rivers. agree some models literature. closest agreement seen developed steep especially highest considered present study. Therefore, it can be concluded that methodology replicated more general this process such as sediments non-uniform shapes sizes. However, simplified is proposed estimate up
