Abstract We present the theoretical and experimental results of water surface wave in a trough with periodical topographic bottom under parametric excitation. There are 19 steps of the same size periodically inserted into the trough. It is found that waveforms observed in the experiment are consistent with theoretical ones. Moreover, some complex and interesting phenomena arise in the experiment due to nonlinearity.
