In this paper the transformations of sea waves, reproduced by a JONSWAP spectrum in a laboratory channel, have been studied both in frequency and time domain. In frequency domain the occurrence of non-linearities producing energy transfers to high and low frequencies was studied. The reported experimental results enabled us to comparate the two approaches and to define the limits within which they give the same results.
