This up-to-date and comprehensive account of theory and experiment on
wave-interaction phenomena covers fluids both at rest and in their shear
flows. It includes, on the one hand, water waves, internal waves, and
their evolution, interaction, and associated wave-driven means flow and,
on the other hand, phenomena on nonlinear hydrodynamic stability,
especially those leading to the onset of turbulence. This study provide
a particularly valuable bridge between these two similar, yet different,
classes of phenomena. It will be of value to oceanographers,
meteorologists, and those working in fluid mechanics, atmospheric and
planetary physics, plasma physics, aeronautics, and geophysical and
astrophysical fluid dynamics.
