Definition: propagation velocity of water wave groups and the wave energy

Note 1 to entry: The group velocity of a water wave is the velocity at which the energy associated with the wave disturbance travels in the direction of wave propagation. In deep water using linear wave theory the group velocity is one half the wave phase velocity. In shallow water the group velocity is equal to the wave phase velocity.
