Abstract
— Flume experiments are performed to investigate the process of development of alternate bars under unsteady flow conditions. The bed response to unsteady flow is analyzed for different values of the period of the flood and the observed temporal behaviour of the amplitude of bars, which appears to be strongly affected by the unsteady character of the flow, is compared with the theoretical predictions of Tubino and Seminara [1987].
