A system of differential equations is derived from Biot's constitutive and motion equations for a poroelastic material and a model for a one‐layer seabed is constructed. A normal modes representation for pressure in the far field is found in the case of constant parameters. The model's prediction for transmission loss is examined for five different types of sediments and compared to the predictions of a solid elastic halfspace model.
