A probabilistic full waveform inversion of surface waves

Geophysical Prospecting, Volume 72, Issue 9, Page 3448-3473, November 2024.
Abstract Over the past decades, surface wave methods have been routinely employed to retrieve the physical characteristics of the first tens of meters of the subsurface, particularly the shear wave velocity profiles. Traditional methods rely on the application of the multichannel analysis of surface waves to invert the fundamental and higher modes of ...

Integration of ground geophysical methods to characterize near‐surface aquifer zones within an active mine

Near Surface Geophysics, Volume 22, Issue 5, Page 521-538, October 2024.
Abstract Understanding near‐surface groundwater storage, flow patterns, surface and groundwater interactions in mining areas can assist in making mining more efficient and profitable. This is especially important in opencast mines affected by water inflows that may negatively affect production and increase mining costs. We map and characterize the near‐

Application of high resolution geophysical prospecting to assess the risk related to subsurface deformationin Mexico City [PDF]

Proceedings of the International Association of Hydrological Sciences, 2015
In the eastern sector of Mexico City the sub soil consists of high contrasting sequences (lacustrine and volcanic inter bedded deposits) that favor the development of erratic fracturing in the surface causing damage to the urban infrastructure.

Slope failure remediation using constrained horizontal‐to‐vertical spectral ratio inversion techniques

Geophysical Prospecting, Volume 72, Issue 8, Page 3157-3167, October 2024.
Abstract Slope failure rates may be exacerbated by increased precipitation patterns associated with climate change. Such events are extremely disruptive for local communities affected. Rapid engineering remediation solutions generally require immediate site characterization, including information on depth to intact bedrock and groundwater conditions ...

Investigation of Dam Safety Making Use of Multichannel Analysis of Surface Wave (MASW) Seismic Method

, 2013
Multichannel Analysis of Surface Wave (MASW) seismic method is widely used in geotechnical engineering for the measurement of shear wave velocity and evaluation of material property. This method was recently conducted at a Dam site located in Zaria, within the basement complex of northern Nigeria.

MASW (Multichannel of Analysis of Surface Waves) Measurements on Very Dense Fill of Freeport Mining

Journal of Physics: Conference Series
Abstract The MASW (Multi-Channel Analysis of Surface Waves) was conducted on fill soil at Tembagapura Freeport Mining. The fill was very dense and is the landfills where people dumped waste disposal like car tire rubber etc. Several attempts were made to make boreholes to collect soil samples and to run SPT (Standard Penetration Test ...

Hydro‐Mechanical Characterization of a Fractured Aquifer Using Groundwater Level Tidal Analysis: Effect of Pore Pressure and Seismic Dynamic Shear Stresses on Permeability Variations

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 8, August 2024.
Abstract Groundwater level tidal analysis is a powerful technique to monitor aquifer's permeability and hence its change over time. Earthquakes are known to affect aquifer's properties, in their vicinity through static stress changes but also further away through dynamic stresses.
