Atmospheric noise of a breaking tidal bore.
A tidal bore is a surge of waters propagating upstream in an estuary as the tidal flow turns to rising and the flood tide propagates into a funnel-shaped system. Large tidal bores have a marked breaking roller. The sounds generated by breaking tidal bores were herein investigated in the field (Qiantang River) and in laboratory. The sound pressure record showed two dominant periods, with some si...
متن کاملA Numerical Simulation of a Tidal Bore Flow
A numerical model was developed based on the Cubic-Interpolated Pseudo-particle (CIP) Combined Unified Procedure (CIP-CUP or C-CUP) method equipped with a Large Eddy Simulation (LES) model and a re-initialization method. The model was validated and applied to the tidal bore flow with a weak breaking front. In the tidal bore flow, the model equipped with a LES turbulence model reproduced accurat...
متن کاملFlow Field in a Tidal Bore: a Physical Model
Abstract: A tidal bore may form in a converging channel with a funnel shape when the tidal range exceeds 6 to 9 m. The advancing surge has a major impact on the estuarine ecosystem. Physical modelling of an undular bore has been conducted based upon a quasisteady flow analogy. The experimental data highlight rapid flow re-distributions between successive wave troughs and crests as well as large...

Lubin), glock [email protected] (H. Chanson). A tidal bore is a natural and fragile phenomenon, which is of great importance for the ecology of an estuary. The bore development is closely linked with the tidal range and...
متن کاملSmall-bore Rifle Bullet Wounds
WE are all, I suppose, a little prone to assume that what is new to us is necessarily new to everyone else; and that of what we have lately learned others must necessarily be ignorant. The mere fact that I mention such a truism may, however, be taken as a proof that I do not share in the belief. In this South African caapaign-rather prematurely called in some quarters the Transvaal war-there ar...
