Twin mesospheric bores observed over Brazilian equatorial region [PDF]

Annales Geophysicae, 2016
Two consecutive mesospheric bores were observed simultaneously by two all-sky cameras on 19 December 2006. The observations were carried out in the northeast of Brazil at two different stations: São João do Cariri (36.5° W, 7.4° S) and ...

Inundation, runup and flow velocity of wavemaker generated bores on a planar beach

Journal of Fluid Mechanics, 2023
Undulating and breaking bores are generated in the laboratory using a programmable long-stroke wavemaker. By changing the stroke length and the speed of the wavemaker, both non-decaying and decaying bores are generated and studied.

Undular bores generated by fracture. [PDF]

Physical Review E, 2020
Undular bores, or dispersive shock waves, are nonstationary waves propagating as oscillatory transitions between two basic states, in which the oscillatory structure gradually expands and grows in amplitude with distance traveled.

Run-up and inundation generated by non-decaying dam-break bores on a planar beach

Journal of Fluid Mechanics, 2021
Non-decaying bores are generated in a laboratory using a dam-break system with different reservoir length and depth ratios at the dam-break gate. The experimental data show the dependency of inundation depth, run-up height and flood duration on the ...

Numerical and analytical study of undular bores governed by the full water wave equations and bidirectional Whitham–Boussinesq equations

The Physics of Fluids, 2021
Undular bores, also termed dispersive shock waves, generated by an initial discontinuity in height as governed by two forms of the Boussinesq system of weakly nonlinear shallow water wave theory, the standard formulation and a Hamiltonian formulation ...

Investigation into the Cause of Iron-Related Clogging of Groundwater Bores Used for Viticulture in the Limestone Coast, South Australia

Water, 2021
Iron-related clogging of boreholes, pumps and dripper lines is a significant and costly problem for irrigators worldwide. The primary cause of iron-related clogging is still debated. Previous studies have described complex interactions between biological

Observations of Shoaling Nonlinear Internal Bores across the Central California Inner Shelf

Journal of Physical Oceanography, 2020
We present observations of shoaling nonlinear internal bores off the coast of central California. The dataset includes 15 moorings deployed during September–October 2017 and cross-shore shipboard surveys.

Deep Rolling of Bores Using Centrifugal Force

Engineering Proceedings, 2022
Deep rolling is a mechanical surface treatment for the specific modification of edge zone properties. In this process, the surface is plastically deformed by a rolling element. The roughness, residual stresses and hardness in particular can be positively

Alongshore Variability of Shoaling Internal Bores on the Inner Shelf

Journal of Physical Oceanography, 2020
Temperature and velocity measurements from 42 moorings were used to investigate the alongshore variability of nonlinear internal bores as they propagated across the central California inner shelf. Moorings were deployed September–October 2017 offshore of
