Popis:	A scheme of model experiments on differentially rotating free-surface shallow water is proposed for discovering and studying the over-reflection instability. The scheme allows suppressing two stronger instabilities possible in the simulations, i.e., Kelvin–Helmholtz and centrifugal instabilities which the authors have studied earlier in rotating shallow water both theoretically and experimentally. Distinctive features of coherent structures to be generated by the over-reflection instability are figured out. Being observed in the laboratory simulations, the features will evidence that this very instability does exist.
