TRANSFORMATION OF WAVE GROUPS AND ACCOMPANYING LONG WAVES IN SHALLOW WATER

M. Mizuguchi, H. Matsutate

Abstract


Interaction of short waves modulation and long waves evolution is studied. Existence of free long waves is taken into account. Laboratory experiment and numerical simulation with coupled equations are performed. Mechanism of the modulation is discussed. The distance, below which the modulation may be neglected, is evaluated.

Keywords
