Abstract
Over the past four decades, the combination of in situ and remote sensing observations has demonstrated that long nonlinear internal solitary-like waves are ubiquitous
features of coastal oceans. The following provides an overview of the properties of
steady internal solitary waves and the transient processes of wave generation and
evolution, primarily from the point of view of weakly nonlinear theory, of which
the Korteweg-de Vries equation is the most frequently used example. However, the
oceanographically important processes of wave instability and breaking, generally
inaccessible with these models, are also discussed. Furthermore, observations often
show strongly nonlinear waves whose properties can only be explained with fully
nonlinear models.
