Three-dimensional (3D) effects can profoundly influence underwater sound propagation in
shallow-water environments, hence, affecting the underwater soundscape. Various …

In this chapter, an overview of infrasound propagation modeling is presented. The
atmosphere as a propagation medium is discussed with an emphasis on the various …

The Shallow Water Acoustic Modeling (SWAM'99) Workshop was organized to examine the
ability of various acoustic propagation models to accurately predict sound transmission in a …

In this paper, the propagation of a broadband sound pulse in three-dimensional (3D)
shallow water waveguides is investigated numerically. Two cases are examined:(i) the 3D …

The split-step Fourier method is used in three-dimensional parabolic-equation (PE) models
to compute underwater sound propagation in one direction (ie forward). The method is …

The issue of handling a leading-order cross-multiplied term in three-dimensional (3D)
parabolic equation (PE) based models is addressed. In particular, numerical results …
