CHANGES IN HEIGHT OP SHORT WAVES ON LONG WAVES

Michio Sato, Kazuo Nakamura

Abstract


In this paper we describe an experimental study on changes in height of short gravity waves on long waves. Experiments were conducted by making mechanically generated long waves superpose on mechanically generated short waves in a wave flume of 30m long and lm wide. Exact solution by Longuet-Higgins and Stewart explained our experimental results, but approximate expression a'= a,(l+P) which is widely accepted seemed to be inadequate to explain our results.
