Consideration of the Mechanisms for Tidal Bore Formation in an Idealized Planform Geometry [PDF]

Water Resources Research, 2018
A tidal bore is a positive wave traveling upstream along the estuary of a river, generated by a relatively rapid rise of the tide, often enhanced by the funneling shape of the estuary.

Tidal bore revealed by SWOT: a case study from the Severn river [PDF]

Scientific Reports
We utilize Surface Water and Ocean Topography (SWOT) satellite data to derive a complete longitudinal profile of water surface elevations for tidal waves and capture a tidal bore within the Bristol Channel and Severn River system, marking the first such ...

Sediment inception under breaking tidal bores [PDF]

Mechanics Research Communications, 2012
A tidal bore may develop in an estuary during the spring tide conditions when the tidal range exceeds 5-6 m and the flood tide is confined to a narrow funnelled estuary with low freshwater levels.

Atmospheric noise of a breaking tidal bore [PDF]

The Journal of the Acoustical Society of America, 2016
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.

Minimal model for tidal bore revisited [PDF]

New Journal of Physics, 2019
This develops a recent analysis of gentle undular tidal bores (2018 New J. Phys. 20 053066) and corrects an error. The simplest linear-wave superposition, of monochromatic waves propagating according to the shallow-water dispersion relation, leads to a ...

Tidal Bore Scour around a Spur Dike

Journal of Marine Science and Engineering, 2022
Tidal bores are a natural phenomenon with high flow velocity and destructive potential. A spur dike is a widely used river regulation and embankment protection structure that minimizes erosion, promotes deposition, and protects riverbanks.

Undular tidal bores: Effect of channel constriction and bridge piers [PDF]

, 2011
A tidal bore may occur in a macro-tidal estuary when the tidal range exceeds 4.5-6 m and the estuary bathymetry amplifies the tidal wave. Its upstream propagation induces a strong mixing of the estuarine waters. The propagation of undular tidal bores was

Field Measurements of Unsteady Turbulence in a Tidal Bore: the Garonne River in October 2013 [PDF]

, 2015
A tidal bore is an unsteady rapidly-varied open channel flow generated by the swift advance of the early flood tide in a funnel-shaped river estuary when the tidal range exceeds 4.5 to 6 m.

Tidal bore dynamics in funnel‐shaped estuaries [PDF]

Journal of Geophysical Research: Oceans, 2015
AbstractThe formation and dynamics of tidal bores in funnel‐shaped estuaries is investigated from both a global tidal wave scaling analysis and new quantitative field observations. We show that tidal bore occurrence in convergent estuaries can be estimated from a dimensionless scaling parameter characterizing the relative intensity of nonlinear ...
