Abstract
Resonance states of bed in a meandering channel were discussed by applying linear theories of Parker and Hasegawa to many experimental data of bed topography obtained in channels with changing the radius of curvature and the meander length. It was found from the analysis that (1) data of amplitude of a fundamental bed wave in the resonance condition given from the linear theories is not very different from those in other conditions, (2) bell shaped frequency responce of wave amplitude is seen in both the experimental data and theories under conditions of no bars formation as well as bar formation, and (3) the linear solution for phase lag between a channel plan form and the bed wave agrees with experimental data fairly well.
