S U M M A R Y Limitations of imaging using electrical resistivity tomography (ERT) arise because of the difficulty of quantifying the reliability of tomographic images. A major source of uncertainty in tomographic inversion is data error. Data error due to electrode mislocations is characterized by the sensitivity of electrical potential to both source and receiver positions. This sensitivity i...

The goal of this paper is to introduce and design a cost-effective Oil-in-Water (OiW) measuring instrument, which will be investigated for its value in increasing the efficiency of a deoiling hydrocyclone. The technique investigated is based on Electrical Resistivity Tomography (ERT), which basic principle is to measure the resistivity of substances from multiple electrodes and from these measu...

Abstract. Frozen layers within the subsurface of rock glaciers are generally assumed to act as aquicludes or aquitards. So far, this behavior has been mainly defined by analyzing geochemical characteristics spring waters. In work, for first time, we experimentally confirmed assumption executing an infiltration test in a glacier Southern Alps, Italy. Time-lapse electrical resistivity tomography ...

The first results of a research activity focused on the characterisation of the salt water intrusion along the Ionian coast of the Basilicata region (Southern Italy) are shown and discussed in this study. Along the coast there are many Sites of Community Interest (SCI) subjected to a strong incidence of human activities mainly linked to agriculture and tourism. Primary and secondary salinity of...

Abstract At landfill sites, uncontrolled leachate is a serious cause of groundwater and soil contamination at landfills can occur extensively when there are looploopholesin the vertical HDPE (High-density polyethylene) membrane. For this reason, detecting membranes necessary. The conventional electrode running poles approach limited, it reflects distribution resistivity in 2D subsurface profile...
