Geophysical investigation using the 2D Electrical Resistivity Tomography (ERT) was carried out to assess subsurface of Ugoneki and its environs in order investigate for minerals. A total six (6) traverses, 200 m long each, three (3) transverse lines were North-South direction other traverses West-East Wenner electrode configuration. resistivity data acquired along each traverse. The inverted re...

In this study, building failures were investigated in Damaturu metropolis, using Electrical resistivity method which involves, both Vertical Sounding (VES) and Resistivity Tomography (ERT). The study reveal that the area is composed of five geologic layers, are topsoil, clay, sand, sandy-clay, sand. topsoil thickness ranged from 0.7 to 1.9 m has values 127.6 171.5 Ωm. second layer a clay format...

Abstract. Within the critical zone, regolith plays a key role in fundamental hydrological functions of water collection, storage, mixing and release. Electrical resistivity tomography (ERT) is recognized as remarkable tool for characterizing geometry properties regolith, overcoming limitations inherent to conventional borehole-based investigations. For exploring shallow layers, small electrode ...

Mass and energy exchanges between soil, plants and atmosphere control a number of key environmental processes involving hydrology, biota and climate. The understanding of these exchanges also play a critical role for practical purposes e.g. in precision agriculture. In this paper we present a methodology based on coupling innovative data collection and models in order to obtain quantitative est...

Quantitative estimation of subsurface water and ice content values is critical for the understanding modeling permafrost evolution in alpine regions. Geophysical methods permit assessment conditions a noninvasive quasicontinuous manner; particular, combination seismic refraction tomography (SRT) electrical resistivity (ERT) through petrophysical model can quantitatively estimate ground values. ...

This paper summarizes the results of a recent geophysical investigation carried out at Porolissum, which is considered to be one most significant Roman sites in Romania. The survey was within latus dextrum fort, same location that had been subject earlier surveys as well older archaeological excavations (1970s) uncovered multiroom building. A cesium vapor total field magnetometer and multi-elec...

In this paper, an integrated workflow aimed at optimizing aquifer monitoring and management through time-lapse Electric Resistivity Tomography (TL-ERT) combined with a suite of predictive algorithms is discussed. First, the theoretical background approach described. Then, proposed applied to real geoelectric datasets recorded experiments different spatial temporal scales. These include sequence...

The soils and underlying weathered carbonate rock in karstic regions play an important role the infiltration, storage, retention of water nutrients. Because significant heterogeneity karst, use individual geophysical techniques is often not sufficient for unambiguous assessment irregular distributions fractures. In this study, ground penetrating radar (GPR) electrical resistivity tomography (ER...

ABSTRACT A combination of electrical resistivity tomography (ERT) and magnetic gradiometry was selected to examine a hypothesis concerning the presence remains one oldest archaeological churches in Rhineland, located Neuss?Norf, Germany. The gradiometer survey carried out measure vertical gradient field using proton precession magnetometer along several profiles. data were reduced pole; then an...

Operational and safety issues associated with subsiding sinkholes in karst areas start the definition of fractures joints, causing ground weakness. Conventional geotechnical boreholes geological mapping must be complemented indirect subsurface exploration techniques to detail those structures. This work aims use electrical resistivity tomography (ERT) seismic refraction (SRT) near-surface geoph...
