@article{Cheng_Kunc_Edwards_2003, title={Sonic Boom Excited Sediment Waves: A Model Study}, volume={31}, url={https://jcaa.caa-aca.ca/index.php/jcaa/article/view/1572}, abstractNote={Sonic boom excited sediment waves are investigated with a model of interacting wave fields comprising water of finite depth and an elastic medium representing the sediment. The latter is assumed to be uniform, isotropic and semi-infinite in extent. The free modes are found to be dispersive, resulting in a finite (non-vanishing) resonance speed range. The study recognizes the difference in the far-field behavior between the excited resonance mode and the wave group of free modes: whereas the excited underwater wave of the resonance mode propagates at the same speed as the sonic-boom air load and remains in the form of a monochromatic wave train, the wave group of the free modes disperses into a wave packet and attenuate with increasing distance and time. Examples of a sediment model of fine sand with sonic boom waves at two flight Mach numbers are discussed. Differences and similarities between the present analysis and Desharnais and Chapman’s study are noted.}, number={4}, journal={Canadian Acoustics}, author={Cheng, H.K. and Kunc, J.A. and Edwards, J.R.}, year={2003}, month={Dec.}, pages={5–16} }
