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.

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 ...

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 ...

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).

Positive Surge Propagation in Sloping Channels [PDF]

open access: yes, 2017
A simplified model for the upstream propagation of a positive surge in a sloping, rectangular channel is presented. The model is based on the assumptions of a flat water surface and negligible energy dissipation downstream of the surge, which is ...

Mechanical Properties and Microstructure of High Ductility Solidified Silt [PDF]

open access: yes长江科学院院报
[Objectives] The silt foundations of Qiantang River seawalls exhibit weak impermeability and are prone to water erosion and loss. During periods of strong tidal bores and floods, soil flowing and piping are likely to occur, leading to seawall defects and

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

open access: yes, 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

SPH modeling of tidal bore scenarios [PDF]

open access: yesNatural Hazards, 2014
The paper presented a smoothed particle hydrodynamics (SPH) method to study the three-dimensional (3D) tidal bore scenarios. The SPH method is a mesh-free particle modeling technique that can track the large deformation of free surfaces in a straightforward and accurate way.

Note on tidal bores [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1908
It was shown long ago by Airy that when waves advance over shallow water of depth originally uniform, the crests tend to gain upon the hollows, so that the anterior slopes become steeper and steeper. Ultimately, if the conditions are favourable, there formed what is be may called a bore .

Three-dimensional modeling of radiative disks in binaries [PDF]

open access: yes, 2013
Circumstellar disks in binaries are perturbed by the companion gravity causing significant alterations of the disk morphology. Spiral waves due to the companion tidal force also develop in the vertical direction and affect the disk temperature profile ...
