The use of open-source processing tools represents a strategic resource for the scientific community. Open Science philosophy (https://www.unesco.org/en/open-science) promotes transparency, reproducibility and accessibility to data source codes. This not only ensures continuous collaborative development, but also increases quality proposed solutions.Characterizing near surface based on geophysical methods is considerable interest many disciplines, reliability provided results tied available...
Tracking the movement of saline tracers by time-lapse electrical resistivity tomography (ERT) has been established as a suitable method in hydrogeological investigations. In our study, we test potential to illuminate discontinuities (i.e., joints, fractures and clefts) bedrock permafrost. Identification such features is key they represent preferential flow paths for water advective heat exchange between atmosphere subsurface permafrost body). Recent studies have suggested that clefts might...
Seismic refraction tomography (SRT) and surface wave analysis (SWA) are two geophysical methods frequently used in near-surface investigations. SRT provides models of the subsurface 2D/3D P-wave velocity distribution, whereas classical SWA approach solves for 1D or pseudo 2D S-wave variation with depth. Optimized acquisition schemes allow joint collection data sets, improving consistency reducing resource requirements. Processing inversion sets commonly carried out separate workflows, only...
The Seewinkel National Park in Burgenland (Austria) encompasses the largest inland soda lakes central Europe. shallow aquifer is confined by an impermeable clay-rich layer, which nourished with salts through capillary upward transport during summer periods. Sinking groundwater levels are responsible for a decline and decrease salt content within unit, threatening ecological state of their rich unique biosphere. Yet, extension hydraulic barrier, its content, changes system accompanying...
Although the hydraulic conductivity is a key parameter to understand landslides, direct methods cannot easily solved with high resolution it at field scale. In this study we present application of induced polarization (IP) method characterize preferential areas for water flow and accumulation in clay-rich landslide. IP provides distribution electrical properties subsurface extensive laboratory investigations have demonstrated its sensitivity textural soil (i.e., clay content); thus it’s...
Summary Geophysical methods have proven to overcome the spatial limitations of direct investigations by providing spatio-temporal information about subsurface properties with an adequate resolution in a non-invasive manner. However, resolved models remain qualitative unless subsequently transformed quantitative estimates parameters interest based on petrophysical model. Petrophysical joint inversion (PJI) approaches permit improved estimation hydrogeological simultaneously inverting...
Summary We applied a data fusion strategy based on imaging results obtained from joint inversion of seismic and electric sets, independent induced polarization multichannel analysis surface waves to solve for mechanical petrophysical parameters in shallow landslide Austria. Seismic was used estimate the Poisson's ratio subsurface density model defined by rock, water air contents retrieved inversion. Based these models elastic moduli shear Young's were derived characterize terms material...
