In Underwater Acoustics ray trajectories are calculated solving the set of Eikonal equations, which account for refraction effects due to the dependence of sound speed on range and/or range. Ray amplitudes can be calculated by solvng the transport equation, or by considering each ray as the central axis of a Gaussian beam, and summing up the influences of all beams over the watercolumn. Energy losses are accounted by considering energy losses after boundary reflections and volume absorption.
