Fluid Wave Dynamics - Linear Theory

• Some general wave kinematics
  • Wave modulation and group velocity
  • An alternate interpretation of group speed
  • A dispersive wave train
  • Space-time evolution of a resolved, progressive, plane wave group of variable wave number
  • Special cases
    • Non-dispersive wave group
    • Centered disturbances
    • Short gravity waves
    • Capillary waves
    • Short waves near the minimum group speed
    • Dispersion of a plane Tsunami wave
