Abstract: We ran flume experiments with constant water discharge and sediment feed rate at the inlet. Experiments were conducted over long times (typically 600 h). The bars migrated downstream intermittently, producing the most important pulses. When the bar position was stable for a few hours, additional pulses resulted from sediment transfer from pool to pool, in the form of sediment waves (bedload sheets).
