DESCRIPTION:Internal solitary waves (ISWs) are non-sinusoidal\
 , finite-amplitude waves that propagate along dens
 ity interfaces in stably-stratified fluids.   They
  are ubiquitous features of many of the world’s sh
 allow seas\, where they are observed most frequent
 ly as “internal solitary wave packets” that propag
 ate over hundreds of kilometres without change in 
 form.  Their propagation is associated with the ge
 neration of significant velocity shear in the affe
 cted water column and with associated perceived th
 reats to the integrity and operation of offshore e
 xploration and production platforms.  In many case
 s the amplitude of the solitary waves is comparabl
 e with the depth of the water column\, such that t
 he presence of the bottom boundary can play an imp
 ortant role in the wave behaviour and development.
   The results of a series of linked modelling inve
 stigations into aspects (boundary jet generation\,
  shear instability and wave breaking) of this deve
 lopment will be described.
