Correlation between field electrical resistivity and geotechnical SPT blow counts at tropical soils in Brazil
(2021-12-01)
The joint application of geophysical investigations, non-invasive methods, and geotechnical investigations, invasive methods, in order to interpret the geological features in subsurface has been increasingly accepted, ...
Electrical resisitivity to detect zones of biogas accumulation in a landfill
(2015-01-01)
Biogas produced in sanitary landfills consists in a potential source, formed by degradation of organic matter, this gas is constituted by CH4, CO2 and water vapor. Sanitary landfills represent important depository of organic ...

(Inst Geophysics Unam, 2015-10-01)
Biogas produced in sanitary landfills consists in a potential source, formed by degradation of organic matter, this gas is constituted by CH4, CO2 and water vapor. Sanitary landfills represent important depository of organic ...
Piping process: Genesis and network characterization through a pedological and geophysical approach
(2020-03-01)
Piping is a soil erosion process initiated by concentrated subsurface water flow, which can develop in both natural and anthropogenic landscapes and causes various environmental impacts. The piping process acts as a relief ...
Analysis of the Physical Integrity of Earth Dams from Electrical Resistivity Tomography (ERT) in Brazil
(2019-01-01)
Dams are structures that barrier rivers and streams for a variety of purposes. The constant maintenance of these structures is essential, since a possible accident can lead to damage of catastrophic proportions. In November ...
Hydraulic conductivity and geophysics (ERT) to assess the aquifer recharge capacity of an inland wetland in the Brazilian Savanna
(2021-12-01)
The inland wetlands can perform the storage of water on the surface and the recharge of aquifers. Even a small wetland can work as a local point of water infiltration, influencing and sustaining the hydrodynamics in the ...
Delineation and Quasi-3D Modeling of Gold Mineralization Using Self-Potential (SP), Electrical Resistivity Tomography (ERT), and Induced Polarization (IP) Methods in Yassa Village, Adamawa, Cameroon: A Case Study
(2022-02-01)
The Lom volcano-sedimentary formation belongs to the Adamawa-Yadé (AYD) domain of the Pan-African fold belt in Cameroon. It is a geological formation presenting mineral deposits of economic potential such as gold and ...
Soil electrical resistivity monitoring as a practical tool for evaluating irrigation systems efficiency at the orchard scale: a case study in a vineyard in Central Chile
(Springer, 2021)
In many orchards, irrigation scheduling is designed based on data from meteorological networks and considering homogeneous soil properties. Such assumptions may result in inefficient irrigation, which is difficult to ...
Delineation of necroleachate pathways using electrical resistivity tomography (ERT): Case study on a cemetery in Brazil
(2021-12-01)
Cemeteries can be considered as potential sources of soil and groundwater contamination in burial sites where there is no collection and treatment system for necroleachate, an effluent rich in organic matter and inorganic ...
Electrical resistivity tomography (ERT) applied in the detection of inorganic contaminants in suspended aquifer in Leme city (Brazil)
(2017-01-01)
The assessment of contamination caused by improper disposal of solid waste involves integrated analysis of the physical environment, which shall range from the location of the pollutant source, flow paths and accumulation ...
