DESCRIPTION:Internal solitary waves (ISWs) are non-sinusoidal\, finite-amp
 litude waves that propagate along density interfaces in stably-stratified 
 fluids.   They are ubiquitous features of many of the world’s shallow se
 as\, where they are observed most frequently as “internal solitary wave 
 packets” that propagate over hundreds of kilometres without change in fo
 rm.  Their propagation is associated with the generation of significant ve
 locity shear in the affected water column and with associated perceived th
 reats to the integrity and operation of offshore exploration and productio
 n platforms.  In many cases the amplitude of the solitary waves is compara
 ble with the depth of the water column\, such that the presence of the bot
 tom boundary can play an important role in the wave behaviour and developm
 ent.  The results of a series of linked modelling investigations into aspe
 cts (boundary jet generation\, shear instability and wave breaking) of thi
 s development will be described.
