Experimental study of the wave propagation and decay in a channel through a rigid ice-sheet
Experiments are carried out in a wave flume, to study wave propagation in a narrow channel
along a barge-like structure, attached to one of the side-walls. By geometric symmetry this is
equivalent to a channel through a rigid ice-sheet, in a tank twice as wide. When both the
draft and width of the channel are small, the wavelength increases dramatically as the
waves enter into it. It is checked that this modification of the wavelength is in agreement with
the theory given by Molin [J. Fluid Mech. 430 (2001) 27]. The slow decrease in amplitude of …
