Correlating Groundwater Level Fluctuations of a Fractured Confined Aquifer With Relative Variations in Seismic Velocity: A Way to Estimate the Groundwater Storage

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Analysis of ambient seismic noise is of increasing interest for its potential to monitor aquifers, seismic wave velocity being sensitive to fluctuations of the water table or to pore pressure variations. The correlation with groundwater pressure variations in confined aquifers, which are often strategic, is an open scientific question, as is ...

Notranja oksidacija Cu-C in Ag-C kompozitov [PDF]

, 2012
The internal oxidation in copper-carbon and silver-carbon composites occurs when they are exposed to air or oxygen at high temperature. Solubility of carbon in copper or in silver is very low.

Geoelectric versus MASW for geotechnical studies

Journal of Earth System Science, 2019
We explore the role of non-invasive multi-electrode electrical resistivity imaging (ERT) and induced polarisation imaging (IPI) as an alternative to multichannel analysis of surface waves (MASW) for geotechnical site characterisation in view of their higher near-surface spatial resolution.

Geophysical imaging of the subsurface seismic structure of the Chestnut Hill Reservoir earth embankment dam (Massachusetts)

Near Surface Geophysics, Volume 23, Issue 2, Page 105-120, April 2025.
Abstract Degradation within a manmade earth embankment structure is often unobservable from the surface. In order to evaluate the structural integrity of earth embankment levees and dams and identify subsurface zones of weakness that may result in the future failures of such structures, various geophysical methods have been proposed as effective ...

Velocity model estimated from seismic refraction survey and MASW, at Flamengos site (Faial island, Azores) [PDF]

, 2014
The aim of this communication is to present the velocity models of propagation of seismic waves P and S using geophysical methods, such as refraction surveys and MASW (Multichannel analysis of surface waves).

The Combination of Hvsr and Masw Methods with Landsat 8 Imagery to Assess the Changing Shoreline along the Coastal Area of Central Bengkulu

TRENDS IN THE SCIENCES
The Central Bengkulu Regency possesses a coastline measuring 21.8 km, situated in direct proximity to the Indian Ocean. The heightened wave and ocean current dynamics possess the capacity to induce detrimental effects in the form of coastal abrasion ...

Multi‐Scale Geophysical Imaging of a Hydrothermal System in Yellowstone National Park, USA

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Little is known about the local plumbing systems that fuel Yellowstone's famous hot springs, geysers and mud pots. A multi‐method, multi‐scale geophysical investigation was carried out in the Obsidian Pool Thermal Area (OPTA) to: (a) delineate the lateral extent of the hydrothermal area and associated surface features; (b) estimate the ...

Influences of variations in the sledgehammer trajectory and collinearity of the geophone array in an MASW survey on the shear-wave velocity profile

International Journal of Geo-Engineering, 2020
In professional activities aimed at seismic site classification, geophysical methods based on measurements of surface waves are often used to measure the shear-wave velocity (Vs), with the MASW survey being one of the most common techniques employed for ...

Sex work advocacy in Aotearoa New Zealand: Advocates’ perspectives on effecting positive change: A research report presented in partial fulfilment of the requirements for the degree of Master of Applied Social Work at Massey University, Manawatu, Aotearoa New Zealand [PDF]

, 2015
Aotearoa New Zealand is in a unique position, being the only country to implement a model of full decriminalisation of sex work. This research explores the perspectives of sex work advocates on how they perceive their roles and the part they play in ...

Surface wave analysis for building near surface velocity models: established approaches and new perspectives [PDF]

, 2010
Today, surface-wave analysis is widely adopted for building near-surface S-wave velocity models. The surface-wave method is under continuous and rapid evolution, also thanks to the lively scientific debate among different disciplines, and interest in the
