Abstract: Wave turbulence in
quasi-1D geometry is usually not investigated experimentally
since low-order resonant wave interactions are theoretically
prohibited. Here, we report on the first observation of
unidirectional capillary-wave turbulence on the surface of a
fluid in a canal. We also show that five-wave interactions are
the lowest-order resonant process subsisting at small scales,
and are thus probably the one generating such quasi-1D capillary
wave turbulence. We show that the wave spectrum is compatible
with the corresponding dimensional analysis prediction. The main
assumptions of weak turbulence theory are also verified
experimentally. Quasi-1D wave turbulence could be thus
highlighted in other fields of wave turbulence.
