Physical Modelling of Breaking Tidal Bores: Comparison with Prototype Data [PDF]

open access: yesJournal of Hydraulic Research/De Recherches Hydrauliques, 2015
A tidal bore is a hydraulic jump in translation, propagating upstream as the tide turns to rising and the flood flow advances in a funnel-shaped river mouth under spring tide conditions. This study focused on the unsteady turbulence induced by a breaking

Unsteady turbulence in tidal bores: Effects of bed roughness [PDF]

open access: yesJournal of Waterway, Port, Coastal and Ocean Engineering, 2010
A tidal bore is a wave propagating upstream as the tidal flow turns to rising. It forms during spring tide conditions when the flood tide is confined to a narrow funneled channel.

Physical modeling of unsteady turbulence in breaking tidal bores [PDF]

open access: yesJournal of Hydraulic Engineering, 2012
A tidal bore is an unsteady flow motion generated by the rapid water level rise at the river mouth during the early flood tide under macrotidal and appropriate bathymetric conditions. This paper presents a study that physically investigates the turbulent

Environmental Impact of Undular Tidal Bores in Tropical Rivers [PDF]

open access: yes, 2005
A tidal bore impacts significantly on the estuarine ecosystem, although little is known on the flow field, mixing and sediment motion beneath tidal bores.

Off-bottom turbulence expansions of unbounded flow over a deep-ocean ridge

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2019
Internal wave breaking upon sloping seafloors is a potential source of turbulent mixing in the deep-ocean, but we lack details on off-bottom breaking. Turbulence processes are relevant for the dispersal away from the seafloor of suspended materials like ...

High Frequency Field Measurements of an Undular Bore Using a 2D LiDAR Scanner

open access: yesRemote Sensing, 2017
The secondary wave field associated with undular tidal bores (known as whelps) has been barely studied in field conditions: the wave field can be strongly non-hydrostatic, and the turbidity is generally high.

Turbulent mixing of particles under tidal bores: An experimental analysis [PDF]

open access: yes, 2010
A tidal bore develops in an estuary when the tidal range exceeds 4.5-6 m and the estuarine bathymetry amplifies the tidal wave. The bore is an abrupt rise in water depth associated with a discontinuity in velocity and pressure fields at the front. Herein

Observation of Optical Undular Bores in Multiple Four-Wave Mixing

open access: yesPhysical Review X, 2014
We demonstrate that wave-breaking dramatically affects the dynamics of nonlinear frequency conversion processes that operate in the regime of high efficiency (strong multiple four-wave mixing).

Impact of and adaptation strategies for sea-level rise on Yangtze River Delta

open access: yesAdvances in Climate Change Research, 2018
The Yangtze River Delta characterized by a dense population and a rapidly developing economy is highly vulnerable to sea-level rise. The data from the China Oceanic Information Network and the Zhejiang Provincial Hydrology Bureau are used to analyze sea ...

Characterization of a Double Mesospheric Bore Over Europe [PDF]

open access: yes, 2017
Observations of a pair of mesospheric bore disturbances that propagated through the nighttime mesosphere over Europe are presented. The observations were made at the Padua Observatory, Asiago (45.9\ub0N, 11.5\ub0E), by the Boston University all-sky ...
