Three-dimensional shear velocity structure of the Mauléon and Arzacq Basins (Western Pyrenees)
BSGF - Earth Sciences Bulletin, 2021 We present a 3-D shear wave velocity model of the Mauléon and Arzacq Basins from the surface down to 10 km depth, inverted from phase velocity maps at periods between 2 and 9 s.

Three‐dimensional seismic velocity structure in the Sichuan basin, China [PDF]
Journal of Geophysical Research: Solid Earth, 2016 AbstractWe present a new three‐dimensional velocity model of the crust in the eastern margin of the Tibetan Plateau. The model describes the velocity structure of the Sichuan basin and surrounding thrust belts. The model consists of 3‐D surfaces representing major geologic unit contacts and faults and is parameterized with Vp velocity‐depth functions ...

Numerical investigation of the three-dimensional velocity fields induced by wave-structure interaction [PDF]
ITM Web of Conferences, 2019 Submerged shore-parallel breakwaters for coastal defence are a good compromise between the need to mitigate the effects of waves on the coast and the ambition to ensure the preservation of the landscape and water quality.

Three-Dimensional Shear Wave Velocity Structure of the Northeastern Brazilian Lithosphere
International Journal of Geosciences, 2016 A large number of Rayleigh wave dispersion curves recorded at twenty three seismic stations was used to investigate the 3-D shear wave velocity structure of the northeastern Brazilian lithosphere. A simple procedure to generate a three-dimensional image of Mohorovicic； discontinuity was applied in northeastern Brazil and the Moho 3-D image was in ...

Three‐dimensional velocity structure of the polar wind [PDF]
Journal of Geophysical Research: Space Physics, 2002 A three‐dimensional, time‐dependent, fluid model was used to investigate the velocity structure of the global ionosphere–polar wind system. Each simulation involved following a large number of high‐latitude flux tubes (over 1000) as they moved under the influence of convection and corotational electric fields.

Three‐dimensional velocity structure of the Kilauea Caldera, Hawaii [PDF]
Geophysical Research Letters, 1999 High‐resolution velocity models (0.5 km resolution) of the Kilauea caldera region are obtained by the tomographic inversion of both P‐ and S‐wave arrival times. Data are from the permanent Hawaiian Volcano Observatory (HVO) seismic network, a broadband seismic network, and a temporary array of stations centered on the southern boundary of the caldera ...
