Abstract
Statistical characteristics of the modification in random wave field due to intensified nonlinearity in the surf zone and sequential breaking was investigated using Run 1 of Kraus et al.. It turns out that envelope and radiation stresses distribution are severely modified by intensified nonlinearity. Once a breaking is activated in random wave field, a hump begins to be formed in envelope distribution. We also found that the water level rise induced by the excessive momentum flux deficit in waves approaching from a breaker line also have profound effects on phase distribution. With a depth as the length scale of prevailing turbulence in the surf zone, the spectrum of fluctuating velocity was estimated which indicates that high frequency fluctuation motion of relatively small scale is to be energetic as low frequency fluctuation of large scale.
