Abstract :
A normal-mode method, suitable for practical calculations of transmission loss, is developed for the propagation of underwater sound in a channel with environmental parameters that depend gradually on range, by employing an adiabatic separation of the wave equation. Results are illustrated using a parabolic sound velocity profile which opens up with increasing range.
