An extended Korteweg-de Vries (KdV) equation is derived that describes the evolution and propagation of long interfacial gravity waves in the presence of a strong, space-time varying background. Provision is made in the derivation for a spatially varying lower depth so that some topographic eeects can also be included. The extended KdV model is applied to… (More)
 Observations of internal solitary waves (ISWs) and of their role in sediment resuspension during the Coastal Mixing and Optics 1996 (CMO 96) experiment are reported. The largest resuspension events observed in the experiment can be related to retarded flow under the wave footprint. Two distinctly different periods of resuspension events could be… (More)
Flow patterns of some of the features in the Voyager 1 imaging data for Jupiter appear to be consistent with those predicted by a solitary-wave theory.
