- W2028491337 abstract "The scattering coefficient is one of the most fundamental parameters by which to quantify the scattering intensity for waves as a function of scattering angle and wave frequency. This study presents a derivation of the scattering coefficient for linear long-wave tsunami equations in randomly fluctuating sea-bottom topography using the first-order Born approximation. The scattering coefficient is directly related to the power spectrum density function of fluctuations in the bottom topography and shows a strong tsunami-wavelength dependence. The scattering regime is determined by the normalized wavenumber ak, where k is the tsunami wavenumber and a is the correlation distance of the fluctuating sea-bottom topography. The scattering pattern for small wavenumbers, ak≪ 1, is symmetric in the forward and backward directions, whereas the pattern for large wavenumbers, ak≫ 1, shows small-angle scattering around the forward direction. Based on the theoretically derived scattering coefficient, we evaluate the excitation of tsunami coda and leading-wave attenuation as a function of the normalized wavenumber. The coda energy for small wavenumber ak≪ 1 is proportional to k3, whereas the energy for large wavenumber ak≫ 1 is proportional to k−p+3 when the power spectral density function of the sea-bottom fluctuation is characterized by a power law with the exponent of −p in large wavenumber. The scattering attenuation represented by the inverse of the quality factor ScQ−1 is proportional to k2 for small wavenumber ak≪ 1, whereas ScQ−1 is proportional to k−p+2 for large wavenumber ak≫ 1." @default.
