Internal solitary waves (ISWs) are non-sinusoidal, finite-amplitude waves that propagate along density interfaces in stably-stratified fluids. They are ubiquitous features of many of the world’s shallow seas, where they are observed most frequently as “internal solitary wave packets” that propagate over hundreds of kilometres without change in form. Their propagation is associated with the generation of significant velocity shear in the affected water column and with associated perceived threats to the integrity and operation of offshore exploration and production platforms. In many cases the amplitude of the solitary waves is comparable with the depth of the water column, such that the presence of the bottom boundary can play an important role in the wave behaviour and development. The results of a series of linked modelling investigations into aspects (boundary jet generation, shear instability and wave breaking) of this development will be described.
