Undular tidal bore dynamics in the Daly Estuary, Northern Australia
Measurements in the macro-tidal Daly Estuary show that the presence of an undular tidal bore contributed negligibly to the dissipation of tidal energy. No recirculation bubble was observed between a trough and the following wave crest in the lee waves following the undular bore. This differs to stationary undular bores in laboratory experiments at larger Froude numbers where a recirculation bub...
متن کاملAtmospheric 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 کاملCirculation and larval distribution in internal tidal bore warm fronts
Internal tidal bore warm fronts were observed during the summer of 1996 off the coast of Southern California. Warm bore fronts had concentrating currents resulting from high-frequency internal motions and from a larger twoway flow; the two-way flow featured surface currents onshore and bottom currents offshore. A sharp thermocline depression and high-frequency, large-amplitude internal motions ...
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...
