The article explores how bedload transport in mountain streams can vary widely, impacting natural hazards and sediment issues. The researchers conducted experiments in a flume to study the interactions between bedload transport and bedform dynamics. They found that accelerometers are a cost-effective way to measure bedload discharge rates accurately. By analyzing the bedload data, they identified different time scales related to bedload transport processes. The development and migration of alternate bars in the flume were shown to have a significant impact on bedload transport rate fluctuations.
