Abstract

Discusses the effects of nonstationarity, for cases where nonlinearity and irregularity are both weak. Examines the evolution of unidirectional waves in deep water, using multiple scale analysis, obtains evolution equations governing the wave envelope and generated long waves. Solves these equations for one-dimensional propagation of a wave packet and two-dimensional modulational instability/wave packet evolution. Examines also long wave generation by short waves scattered by a submarine ridge. Nonlinearity enhances long waves which can be resonated on the ridge. (C.J.U.)
