Abstract
The effects of bottom (water–sediment interface) roughness on low-frequency sound propagation is examined using a theory of scattering based on boundary conditions applied at the mean boundary. Boundary roughness effects on normal mode attenuation coefficients are examined for two sediment types and two frequencies. For the cases studied it was found that, for fixed bottom roughness, the attenuation coefficients increased with frequency as expected, but showed insensitivity to the correlation length of the bottom roughness. It was also determined that, for fixed bottom roughness, a harder sand-type bottom produced more scattering attenuation than a clay-type bottom.
